Our other modalai seems to working fine. ## Reply by Eric Katzfey (ModalAI staff) · 2021-10-27 16:08:36 UTC 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? ## Reply by Guest · 2021-10-27 17:47:28 UTC 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 ## Reply by ashwin-umdlife · 2021-10-27 20:19:32 UTC Thanks for th quick reply. Highly appreciate it.
