I have been experimenting with Trigger.io and was successfully using it last week.
However, I have been trying new stuff out today, and have been unable to open the Trigger Toolkit properly. I'm not sure why - maybe I deleted something by accident.
The error returned was as follows:
Error in remote call to app.list: Expecting property name: line 25 column 2 (char 482) Details Close

I have tried uninstalling and reinstalling the toolkit a few times, but no joy.
Any help/ advice much appreciated.
Thanks

So I figured this out, I was being a bit stupid:
I had to access hidden files on my Mac to find the Users/josholdham/Library/Trigger Toolkit folder, which I then deleted.
Launching Toolkit again then worked fine.
This is how we find hidden files on the Mac, in case it isn't clear.

Hope that helps some people - thanks to all previous helpers for guidance.
That looks like src/config.json is malformed in one of your apps.
I'd recommend looking at src/config.json in your apps' directories and checking the JSON syntax around line 25.
In the future, you can avoid these problems by using the App Config tab in the Toolkit to change the config, rather than editing src/config.json directly.

I'm having trouble deploying a flask app to the Google app engine. It works fine when I run it locally but as soon as it's deployed to the app engine it fails. With two exceptions (I'm always getting both, I'm unsure which one comes first).

It consistently happens within the __init__ function of a form. And specifically in there when I try to append a validator to a validators list.
self.password.validators.append(InputRequired(message='Please enter password!'))
It is not specific to this one validator, the same thing happens with others too. I am at a complete loss as to why and how appending validators would interact with SMTP or sockets.
One thing I noticed is that I had an issue with the Email validator which also worked fine locally but required me to install the module 'email_validator' to work. When I did that it complained that it couldn't use append on a tuple when I tried to append a validator to - what was a list in my local app - but for some reason turned out to be a tuple when I ran the exact same code on the app engine. I removed the Email validator (and the import/requirements) entirely and now I'm at the problem I've described above. It may or may not be related to the Email validator issue.
Update: The error message does indeed seem to be related to the validators.append() call seeing as by setting up the validators at object creation and avoiding all further changes via validators.append() fixed the problem for me. This is the requirements.txt that goes with the application:
blinker>=1.4
Click>=7.0
Flask>=1.1.1

python-dotenv>=0.11.0
SQLAlchemy>=1.3.13
Werkzeug>=1.0.0
WTForms>=2.2.1
Instead of a full minimal, reproducible example I can offer a minimized version of the form that was causing the issues when instanciated on the GAE:
class ExampleForm(FlaskForm):
name = StringField('Name')
original_name = HiddenField('Original Name')
def add_validators(self):
names = [a.name for a in Users.query.all()]
if self.original_name.data:
names.remove(self.original_name.data)
self.name.validators.append(InputRequired(message='Please enter name!'))
self.name.validators.append(NoneOf(names, message='Username already exists!'))
def __init__(self):
super().__init__(*args, **kwargs)
self.add_validators()
As I'm writing this it occurs to me that maybe I need to always initialize an empty validators list on creation to ensure new entries can be appended to it (like with a normal list) like this name = StringField('Name', validators=[]). I'd still be confused as to why it works locally, but if it fixes the problem that'd be what really counts for me.
I'm using pydicom (installed with pip3, on python 3.7, using Idle) and I need to access pixel_array values.
I just copy-paste the example provided into the documentation and this leads to two errors:
first is about the get_testdata_files operation, which is not working because

second is about the pixel_array and I'm not so able to decode what is wrong, but it seems like the pixel_array is not populated. However I'm able to access other fields in the dataset and the file can be displayed (using ImageJ for example).

Could you help me to solve these two errors and access pixel_array values?
Don't hesitate to give me some advices /remarks/...
Thanks!
Hi Marc welcome to SO!
Your first error means that the get_testdata_files returns an empty list, so your file is not found. Have a look at the pydicom source, it shows that a search is performed in [DATA_ROOT]/test_files. Is your file located in that path?
Your second error is related to PIL and that can be quite difficult to debug and fix. First try to read the pixel_array from a dataset created from one of the supplied test files. If that works, your problem is probably that PIL cannot handle the specific encoding of your image data. You want to install and use GDCM instead of PIL to see if that solves the problem. Another user has had a similar issue as you, GDCM solved the problem. It can be a bit of a headache to get working unfortunately. Or have a look at this page, it shows some other alternatives on viewing the image data.
I cleared all entities from the datastore and cleared the memcache, created an entity using the API Explorer and then attempted to create another one of the same kind in the Datastore console running on localhost:

Any hints as to what might be wrong?
I think it's a bug in the Datastore console.
I was able to replicate the same error on my machine. If you look at the traceback in the exception, you see (fourth from the bottom):
File "/.../google-cloud-sdk/platform/google_appengine/google/appengine/tools/devappserver2/admin/datastore_viewer.py", line 760, in get
count=20)
If you look at that file from line 735, you see:
def get(self, entity_key_string=None):
super(DatastoreEditRequestHandler, self).get(entity_key_string)
if entity_key_string:
entity_key = datastore.Key(entity_key_string)
entity_key_name = entity_key.name()
entity_key_id = entity_key.id()
namespace = entity_key.namespace()
kind = entity_key.kind()
entities = [datastore.Get(entity_key)]
parent_key = entity_key.parent()
if parent_key:
parent_key_string = _format_datastore_key(parent_key)
else:
parent_key_string = None
else:
entity_key = None
entity_key_string = None
entity_key_name = None
entity_key_id = None
namespace = self.request.get('namespace')
kind = self.request.get('kind')
entities, _ = _get_entities(kind,
namespace,
order=None,
start=0,
count=20) ### line 760 #######
...
In that last line, kind is supposed to be string containing the model name of the model you are working with. Instead, if you follow the traceback down into that function call, you see that kind is an empty string. I don't think there's much you can do to fix it at this time. I'd recommend using the interactive console for now to create/edit your Datastore entities, and just use the viewer to view them. I'm sure Google will fix this with an update soon.
Edit: I actually found a hacky fix if you really want the Datastore console to work, but I would still recommend just using the interactive console. The hacky fix is you manually enter the kind variable into the URL sent by the Datastore console.
When you click "Create New Entity" and get the error you show in your question, look at the url:
http://localhost:8000/datastore/edit?kind=&next=http%3A%2F%2Flocalhost%3A8000%2Fdatastore%3Fkind%3DUnique
You see ...:8000/datastore/edit?kind=&.... Right there, just type in the model name. For example, let's say your model name is User:
http://localhost:8000/datastore/edit?kind=User&next=http%3A%2F%2Flocalhost%3A8000%2Fdatastore%3Fkind%3DUnique
This brought me to the "Create new entity" form for class User (one of my models), and I was able to create a user with that form.
P.S. You may want to also change the model name on the very end of that url (where mine says Unique) to match the kind you are creating, because that model name is the kind that will be displayed after you create your new entity. So mine created a User, but then displayed the Unique entities (Unique is one of my model names).
After updating to GAE 1.8.8 and the GCS Client to r127 my code that displays images no longer works using the Development Server or Production. Code that worked previously now throughs the following error in development:
Blob with key 'encoded_gs_file:blahblahblah' does not exist
Note blahblahblah is just my shorthand for a long string.
Below is how I generate my url. This has always worked in the past.
bkey = blobstore.create_gs_key('/gs/mybucket/myfile.jpg')
url = images.get_serving_url(bkey, size=170, crop=True, secure_url=True)

Reading the release notes for GAE 1.8.8 I cannot see anything else I need to change in my code. Any pointers as to what I am doing wrong would be great.
I'm getting this error... "ImportError: Could not find 'input_readers' on path 'map reduce'" when trying to Run my map reduce job via the http://localhost:8080/mapreduce launcher page.
It looks like my problem is similar to this post, AppEngine mapper API import error. Unfortunately, no definitive answers were given.
I've simplified it down to this tiny testmapreduce.py:
from google.appengine.ext import db
class TestEntity(db.Model):
value = db.StringProperty()
def mapperhandler(test):
print test.value
return
And my mapreduce.yaml:
mapreduce:
- name: Simplest MapReduce
mapper:
handler: testmapreduce.mapperhandler
input_reader: mapreduce.input_readers.DatastoreInputReader
params:
- name: entity_kind
default: testmapreduce.TestEntity
One possible clue is the presence of __init__.py has no effect (whether in the project root, the mapreduce directory, or both). I'm sure I'm making a beginner mistake, but over the last couple of days I have read every bit of documentation, and all the examples I can find. Thanks.
UPDATE:
I get the same error trying to invoke it via...
control.start_map(
"Give awards",
"testmapreduce.mapperhandler",
"mapreduce.input_readers.DatastoreInputReader",
{"entity_kind": "testmapreduce.TestEntity"},

UPDATE:
As requested, the stack trace -- let me know what else would be helpful...
