error thrown on successful saveChanges() call [breezeJS] - angularjs

I use breeze.angular to communicate with an olingo OData provider. After changing properties of an Entity I have a pending change. The corresponding object is visible when manager.getChanges() is called.
Calling manager.saveChanges in fact results in successful update of the database through olingo. But simultaneously the following error gets thrown:
TypeError: Cannot read property 'entityAspect' of undefined

at wrappedCallback (http://localhost:63342/js/angular.js:11319:81)
Apparently breeze is unable to change the entityState, as the objects remain pending changes.
Regarding the http communication I observed two Server requests:
Request Method:OPTIONS
Status Code:200 OK
and
Request Method:POST
Status Code:202 Accepted
Why is breeze unable to transact this succesful update?
UPDATE:
Added saveChanges code.
(I removed my own logging methods off the callbacks.)
manager.saveChanges()
.then(saveSucceeded)
.catch(saveFailed)
.finally(saveFinal);
function saveSucceeded(saveResult) {
console.log(saveResult);
}
function saveFinal(saveFinal){
console.log(saveFinal);
}
function saveFailed(error){
console.log(error);
}
saveFailed receives the TypeError above, while saveFinal is undefined.
result object:
{
"d":{
"__metadata":{
"id":"http://localhost:8080/targit2/targit2.svc/Applicationlocations(applicationID=2332,locationID=6)",
"uri":"http://localhost:8080/targit2/targit2.svc/Applicationlocations(applicationID=2332,locationID=6)",
"type":"targit2.Applicationlocation"
},
"applicationID":2332,
"locationID":6
}
}

Breeze uses datajs to convert data to and from the OData formats. I suspect that datajs is having trouble coping with the response from Olingo.
I think Olingo originated with SAP, and this SO post describes a problem with that server.

Logic App not able to deserialized Azure data factory pipeline error message

I am facing the below issue with Azure Data Factory using Logic App.
I am using the Azure Data Factory pipeline for migration and Logic App for sending "Success & Failure" notification to the technical team.
Now success is working fine as the message is hardcoded, but failure is not as the Logic App web activity is not able to parse data factory pipeline error.
Here is the input that is going to Logic App web activity
Input
{
"url": "https://xxxxxxxxxxxxxxxxx",
"method": "POST",
"headers": {},
"body": "{\n \"title\": \"PIPELINE RUN FAILED\",\n \"message\":\"Operation on target Migration Validation failed: Execution fail against sql server. Sql error number: 50000. Error Message: The DELETE statement conflicted with the REFERENCE constraint \"FK_cmclientapprovedproducts_cmlinkclientchannel\". The conflict occurred in database \"Core7\", table \"dbo.cmClientApprovedProducts\", column 'linkclientchannelid'.\",\n \"color\": \"Red\",\n \"dataFactoryName\": \"LFC-TO-MCP-ADF\",\n \"pipelineName\": \"LFC TO MCP MIGRATION\",\n \"pipelineRunId\": \"f4f84365-58f0-4da1-aa00-64c3a4daa9e1\",\n \"time\": \"2020-07-31T22:44:01.6477435Z\"\n}"
}
Here is the error logic app is throwing
failures
{
"errorCode": "2108",
"message": "{\"error\":{\"code\":\"InvalidRequestContent\",\"message\":\"The request content is not valid and could not be deserialized: 'After parsing a value an unexpected character was encountered: F. Path 'message', line 3, position 202.'.\"}}",
"failureType": "UserError",
"target": "Send Failed Notification",
"details": []
}
I have tried various options, like set variable and convert by using various existing methods (string, json, replace etc), but no luck
e.g #string(activity('LOS migration').Error.Message)
Struggling almost all day this...please suggest if anyone faced a similar issue...
Below is the data flow activity
now it is working...
Pasting body content into the body text field box WITHOUT clicking on 'Add Dynamic Content' in web activity calling Logic App.
For the failure case, pass the error output use #{activity('LOS migration').error.message.
For sending email, it doesn't know if it's going to send a failure or success email. We have to adapt the body so the activity can use parameters, which we'll define later:
{
"DataFactoryName": "#{pipeline().DataFactory}",
"PipelineName": "#{pipeline().Pipeline}",
"Subject": "#{pipeline().parameters.Subject}",
"ErrorMessage": "#{pipeline().parameters.ErrorMessage}",
"EmailTo": "#pipeline().parameters.EmailTo"
}
We can reference this variables in the body by using the following format: #pipeline().parameters.parametername. For more details, you could refer to this article.
If you want to use the direct error message of the data factory activity as an input to the logic app email expression, you could try.
"ErrorMessage": "#{string(replace(activity('activity_name').Error.Message, '"',''''))}"
Replace 'activity_name' with your failing activity name.

CodenameOne - how to catch HTTP 404 error using Terse REST API

How can I catch an HTTP 404 error using the Terse REST API in CodenameOne? At the moment the default error handler gets this but I would like to display my own message instead. The code I am using is fine if the accountNo exists and I can deal with the resulting JSON, but if not I get the standard error handler displaying the 404 error:
Response<Map> jsonData = Rest.get( URL + "lookup").
jsonContent().
queryParam("account",accountNo).
getAsJsonMap();
This seems to be a mistake in that version of the method. It should fail silently without a UI Dialog. We'll fix it for the next update.
Notice that jsonData should have the error response code within it as jsonData.getResponseCode().

Thunderbird Lightning caldav sync doesn't show any data/events

when i try to synchronize my caldav server implementation with Thunderbird 45.4.0 and Lightning 4.7.4 (one particular calendar collection) it doesnt show any data or events in the calendar though the last call of the sequence provided the data.
In the Thunderbird error log i can see one error:
Zeitstempel: 07.11.16, 14:21:12
Fehler: [calCachedCalendar] replay action failed: null,
uri=http://127.0.0.1:8003/sap/sports/webdav/appsvc/webdav/services/

js/calCachedCalendar.js
Zeile: 327
the call sequence is as follows (detailed content via gist-links):
Propfind Request - Response
Options Request - Response
Propfind Request - Response
Report Request - Response - Response Raw
The synchronization with other clients like macOS-calendar and ios-calendar works in principle and shows the data. Does anyone has a clue what is going wrong here?
Not sure whether that is the cause but I can see two incorrect things:
a) Your <href/> property has trailing spaces:
<d:href>/sap/sports/webdav/appsvc/webdav/services/server.xsjs/cal/_D043133/EVENT%3A070768ba5dd78ff15458f1985cdaabb1.ics
</d:href>
b) your ORGANIZER property is not a valid URI
ORGANIZER:_D043133
i was able to find the cause of the above issue by debugging Thunderbird as propsed by Philipp. The Report Response has http status code 200, but as it is a multistatus response Thunderbird/Lightning expects status code 207 ;-)
Thanks for the hints!

Camel Reslet Component with async processing

I have a requirement which is as follows:
Accept HTTP POST requests containing XML to a certain URL.
Perform pre-requisite actions such as saving the request XML to a file.
Validate the incoming XML matches the corresponding schema.
If the schema validation fails, synchronously respond with a HTTP 400 response code.
If the schema validation passes, synchronously respond with a HTTP 200 response code.
Pass the XML message on for further processing.
When this further processing completes, asynchronously respond to the caller with a HTTP 200 response code.
This is currently how I have the route configured:
onException(IOException.class)
.log(LoggingLevel.INFO, "Schema validation error on incoming message: ${id}")
.handled(true)
.maximumRedeliveries(0)
.process(schemaValidationErrorProcessor);
from("restlet:http://localhost:" + portNum + "/api/XX/XXX?restletMethod=POST")
.log(LoggingLevel.INFO, "Received message")
.convertBodyTo(String.class)
.multicast()
.parallelProcessing()
.to(SAVE_REQUEST_TO_FILE_QUEUE, PROCESS_PROVISIONING_REQUEST_QUEUE);
from(SAVE_REQUEST_TO_FILE_QUEUE)
.log(LoggingLevel.INFO, "Storing message: ${id}")
.to("file://" + requestLogFolder);
from(PROCESS_PROVISIONING_REQUEST_QUEUE)
.log(LoggingLevel.INFO, "Processing provisioning request: ${id}")
.process(requestGate)
.choice()
.when(header(SYSTEM_STATUS_HEADER).isEqualTo(true))
.unmarshal(xmlParser)
.inOnly("bean:requestHandler?method=handle")
.when(header(SYSTEM_STATUS_HEADER).isEqualTo(false))
.log(LoggingLevel.INFO, "Intentially dropping message")
.endChoice();
The schema validation part is achieved via the .unmarshal(xmlParser) line (I have a JaxbDataFormat object configured elsewhere with the schema set in that). When schema validation fails, an IOException is thrown and this is handled by my schemaValidationErrorProcessor which adds the HTTP 400 to the response.
That is all working fine.
The problem I am having is passing the XML message on for further processing. Basically, I need this to be done asynchronously because when the schema validation passes I need to synchronously respond with a 200 response. The processing that I need to do is in the .inOnly("bean:requestHandler?method=handle") line.
I naively thought that setting the routing to my bean to inOnly would set this to be asynchronous and that main route would not wait for a response. However, this is not the case as when the requestHandler.handle method throws an exception, this is thrown back to the caller of the REST endpoint. I don't want this to happen as I want all of this processing to be done in 'the background' as the consumer will have already received a 200 response.
So, my question is, how would I go about achieving such behaviour? I have thought about using queues etc but ideally would like to avoid such components if possible.
Use Camel Websocket component for asynchronously respond to the caller.
From the Camel documentation:
from("activemq:topic:newsTopic")
.routeId("fromJMStoWebSocket")
.to("websocket://localhost:8443/newsTopic?sendToAll=true&staticResources=classpath:webapp");

camel with netty4-http - EncoderException

I'm using camel 2.14.0 with netty4-http
and I get the following exception.
the scenario is this:
I have a route that sends a request, waits for the response (inOut) and then sends another request.
the first request works, and then the second one fails.
also, if I do it quickly enough after the failure - the first request will also fail.
while debugging a bit (HttpObjectEncoder) - I saw that in the working flow the state of the request is: state = ST_INIT (0)
and in the request that failed it is: ST_CONTENT_NON_CHUNK (1)
which causes the illegal state when the type of message is HttpMessage
is this a bug or is there anything I can configure to fix it?

I managed to identify the problem:
the first request I sent was a GET request with null body.
in the class org.apache.camel.component.netty4.http.NettyHttpProducer -
the method getRequestBody(Exchange exchange) is creating the actual request object from the exchange.
in it - the method "toNettyRequest" in class org.apache.camel.component.netty4.http.DefaultNettyHttpBinding
checks if the body is null, and if so - it is creating a DefaultHttpRequest, and not DefaultHttpFullRequest
when the request reaches the encoder as a result of a writeAndFlush call - the encoder does not clean its state because of this part of the code:
if (msg instanceof LastHttpContent) {
state = ST_INIT;
}
the DefaultHttpRequest is not instanceof LastHttpContent, so the state remains ST_CONTENT_NON_CHUNK and the next request will get an IllegalStateException because the state is not ST_INIT
this bug did not exist in netty-http, it only happened when I moved to use netty4-http
the workaround is simple - use an empty String ("") as body
