I have referred to the following resources:
https://docs.cloud.coinbase.com/exchange/docs/websocket-overview
https://docs.cloud.coinbase.com/exchange/docs/websocket-channels
After I connect to wss://ws-feed.exchange.coinbase.com, I send a subscribe message but it is always rejected by the server.
Example 1:
To coinbase:
{
"type": "subscribe",
"product_ids": [
"ETH-USD",
"ETH-EUR"
],
"channels": [
"level2",
"heartbeat",
{
"name": "ticker",
"product_ids": [
"ETH-BTC",
"ETH-USD"
]
}
]
}
From coinbase: {"type":"error","message":"channel is required"}
Example 2:
To coinbase:
{
"type": "subscribe",
"channels": [{ "name": "heartbeat", "product_ids": ["ETH-EUR"] }]
}
From coinbase: {"type":"error","message":"channel is required"}
Example 3:
To coinbase:
{
"type": "subscribe",
"channels": [{ "name": "status"}]
}
From coinbase: {"type":"error","message":"channel is required"}
Basically, I cannot subscribe to any channel.
Question> What did I do wrong here?
Thank you
Perhaps something is being cached where what you're sending isn't what you think you're sending? Because it worked perfectly for me here.
With wss://ws-feed.exchange.coinbase.com as the url and
{
"type": "subscribe",
"channels": [{ "name": "status"}]
}
as the message.

I'm trying to use the Alexa Smart Home Skill ToggleController v3 interface to build a skill that will open and close my gate. I read the docs, and successfully implemented the sample light bulb tutorial from end to end. https://developer.amazon.com/en-US/docs/alexa/smarthome/smart-home-skill-tutorial.html
Everything worked fine. Then I created a new skill and tried to implement the ToggleController interface, mapping ON and OFF to Open and Close using semantics.
Account linking works fine
Lambda gets called with discover directive when I enable the skill on
my Alexa app
There are no errors in CloudWatch
Alexa Simulator calls the right directives and receives responses with no errors
Schema validates successfully
When I click discover devices, I get "No new devices found".
I checked all devices in the Alexa app and my device is not there.
Below is the discovery response message that my lambda returns - (from CloudWatch).
Does anyone know what I'm doing wrong?

Hey i am new to Avro Schema space, needed to convert Jason Array into Avro Schema.
Below Jason is kind of client which serviceName along-with enabler-
If Enabler is true means that particular service is taken by client
If Enabler is false means that particular service is not taken by client.
{
"clientName": "Haven",
"serviceDetailsList": [
{
"serviceName": "Service1",
"enabled": true
},
{
"serviceName": "Service2",
"enabled": true
},
{
"serviceName": "Service3",
"enabled": true
},
{
"serviceName": "Service4",
"enabled": false
},
{
"serviceName": "Service5",
"enabled": false
},
{
"serviceName": "Service6",
"enabled": true
}
]
}
I worked with below schema but not getting proper response.
"fields":[
{"name": "serviceName", "type": [ "Boolean", "false" ] , "aliases":[
"service1" ]
},
{"name": "serviceName", "type": [ "Boolean", "false" ] , "aliases":[
"service2" ]
}
]
Any help would be appreciated.
Thank you all of you,again i tried and able to get correct scheam. Correct Avro Schema is-
{
"name": "modelData",
"type": "record",
"namespace": "com.hi.model",
"fields": [
{
"name": "clientName",
"type": "string"
},
{
"name": "serviceDetailsList",
"type": {
"type": "array",
"items": {
"name": "serviceDetailsList_record",
"type": "record",
"fields": [
{
"name": "serviceName",
"type": "string"
},
{
"name": "enabled",
"type": "boolean"
}
]
}
}
}
]

During Alexa discovery process, we need to send device details and their capabilities. I am sending light and fan details. Light gets showed up in Alexa App but not the fan. Can you please help me to find what I am doing wrong with the following response.
I used this Alexa documentation for creating response. https://developer.amazon.com/docs/smarthome/connect-a-tower-fan-to-alexa.html

Note: I am just repeating above question below because StackOverflow doesn't allow so much code to be pasted with less description.

I think Alexa.RangeController is currently restricted to US region. So if you are trying to discover devices registered to account outside US, then it looks like that Alexa simply ignores the discovery response with RangeController interface. The way I got around this problem is by switching the user account to US and the device appeared immediately. Give it a try and if you a better solution then please do share.
I'm trying to develop microservices on cumulocity.
I'm following this https://cumulocity.com/guides/microservice-sdk/java/.
I'm able to create the application having this response
"availability": "MARKET",
"id": "23",
"key": "TESTMICRO-microservice-key",
"manifest": {
"imports": [],
"noAppSwitcher": true
},
"name": "TESTMICRO",
"owner": {
"self": "my_tenant/tenant/tenants/management",
"tenant": {
"id": "management"
}
},
"requiredRoles": [
"ROLE_INVENTORY_READ"
],
"roles": [
"ROLE_CUSTOM_MICROSERVICE"
],
"self": "my_tenant/application/applications/23",
"type": "MICROSERVICE"
}
Nevertheless when I try the GET URL/application/applications/23/bootstrapUser it returns me 404 Error.
Anyone that can help me?
You probably need to subscribe the application to the tenant:
POST {{url}}/tenant/tenants/{{tenant}}/applications
Body
{
"application": {
"id": "{APPLICATION_ID}"
}
}
I am trying to reply to the user with this message:
bot.reply(message, {
"attachment":
{
"type": "template",
"payload": {
"template_type": "generic",
"sharable": true,
"elements": [
{
"title": "MY title of bd",
"image_url": "https://storage.googleapis.com/ssfkj.com/undefined",
"subtitle": "undefined/undefinedundefinedn(undefined)",
"default_action": { "type": "web_url", "url": "https://ssfkj.com/profile", "messenger_extensions": true, "webview_height_ratio": "tall", "fallback_url": "https://ssfkj.com/profile" }
, "buttons": [{ "type": "payload", "payload": "DEL__PA_undefined", "title": "View more" }
]
}]
}
}
});
But the bot is sending nothing. What is wrong in my code?
My problem was on this level :
"buttons": [{ "type": "payload", "payload": "DEL__PA_undefined", "title": "View more" }]
The
type property
should have the value
postback
not
payload
