Describe the bug
When opening any video, I get a 400 error status code. This is on a new (first) install in docker.
"Error: non 200 status code. Youtube API returned status code 400. See https://docs.invidious.io/youtube-errors-explained/ for troubleshooting."

Steps to Reproduce

1. Click on any video (for example http://inv.home.lan/watch?v=YJ6yhlEZL7I)
2. See error

Logs
500 error in debug console, lmk if more logs are needed

Screenshots

Additional context

• Browser: N/A
• OS: N/A
• Running in docker compose on a raspberry pi

Did you install inv-sig-helper or followed the doc? https://docs.invidious.io/installation/#docker

[vervamond]

Oh I didn't run docker run quay.io/invidious/youtube-trusted-session-generator, maybe that's the issue. Otherwise I cloned the repo and modified the compose file, and ran the docker container, as is stated in the doc

[vervamond]

Yep that was it, the docs are sometimes a bit difficult to understand for me (though not setting things up at 2am probably would've helped). Hope this helps someone in the future!

Hi, I have the same problem, but running docker run quay.io/invidious/youtube-trusted-session-generator results in following:

According to the documentation, you don't have to run docker run quay.io/invidious/youtube-trusted-session-generator anymore:

MIGRATION NEEDED (NEW): Invidious companion

Invidious companion replace both inv-sig-helper and youtube-trusted-session-generator. You don't need to execute youtube-trusted-session-generator anymore.
