Could you please advise what is going wrong here. Our other modalai seems to working fine.

It looks line the newline / CR characters in the configuration file are incorrect. It looks like it thinks the entire configuration file is a single line. Did you install everything from a Linux host computer?

Hi,

This is a bug with the recently pushed 0.2.5 voxl-streamer, the config file is missing a comma after the conf-version line, a patch will be up shortly, but you can add it yourself to the file in /etc/modalai/voxl-streamer.conf to get it working in the meantime
