Hey people, first of all thanks in advance for the help!
I am currently developing a smart home skill for alexa and running into the problem that the device appears unresponsive in the alexa app aswell for the echo device. I am able to set device properties but the response is always that the device is unresponsive.
I tried to use the Validation Schemas Repository however the schema.json does not look to support e.g. a "AddOrUpdate" response yet.
Some key things to note very briefly before I add the messages that are send across the network:
- I applied most of the best practices mentioned here
- I make great use of the event gateway. For all the request the event gateway returns status 202
Currently I am quite stuck so every help is appreciated. I do not know where this error occures.
Now for some messages:

Since the device is already unresponsive even when opening the app or interacting with the user interface I assume the problem resides in either the lambda function or in one of the two responses mentioned above. I also implemented the ChangeReport message. However, I think it is not the root of the problem. I will happily provide if need be.
Thanks in advance
