mqtt asr_server_mqtt crashes when running test_mqtt #139

Closed Talwar85 closed 3 years ago

Talwar85 commented 3 years ago

Hello, I tried to use the examples in the mqtt-folder, but when I started test_mqtt.py the server crashed with an invalid json error. I followed the example step by step.

msg.payload has an value but "if self.recognizer.AcceptWaveform(msg.payload):" does not seem to trigger in the script.

What is the stacktrace?
