For the bot samples provided, I made a success for the sample 2 echo-bot following the tutorial (https://docs.microsoft.com/en-us/azure/cognitive-services/speech-service/tutorial-voice-enable-your-bot-speech-sdk), but encountered some trouble when turning to 49 qnamaker-all-features. I took the similar steps with the tutorial while additionally filling the appsettings.json with information of a knowledge base I built. But when I ran the bot in VoiceAssistantClient, the returned error is:
Error (ConnectionFailure) : Connection was closed by the remote host. Error code: 1002. Error details: The server returned status code '405' when status code '101' was expected. SessionId: 70fa68f0050240299fdc89844992ddb1
I have changed subscription keys, changed passwords, and even conducted the whole tutorial again, but these methods don't work. Besides, there seems to be no troubleshooting doc that includes this error. Does this "1002+405" error mean that the speech service cannot be applied to this sample of qnamaker or some other problems? How to resolve it? Thanks.
