Error validating event: 'file' is a required property about matrix-stt-bot

[rhetenor]

I messed up with the device ID, now it works! The error confused me and I was looking into the wrong things.

Thanks so much for your help! Hopefully I never have to listen to voice messages again! :)

Can you give me a simple step how to reproduce it? Where did you get it?

[rhetenor]

I've cloned the code and setup a virtualenv since I don't have Docker at my hand. Afterwards I followed the instructions from the README and Wiki configuring everything (including room encryption keys) and run the bot as stated in the Dockerfile with python src/bot.py.

I then tried the bot first with a test voice message through a direct message and afterwards I setup a separate new room invited the bot and sent the message to this room. It always outputs the snippet I've pasted onto the console.

My python version is: 3.9.2 and my matrix-synapse version is 1.96.

Have you installed libolm-dev dependence?

[rhetenor]

Yes, they are installed.
