[Bug]: Yt not working in the web interface

[dbenji]

What happened?

I installed the web interface and the results of any patterns involving Youtube videos provide the same results independently from the link provided. If I run the command via CLI the result is the one expected. Everything is running into a Docker container.

Docker instructions and docker file:

• Idea from https://github.com/coolmast/docker-fabric-web

• • I modified the Docker file adding yt-dlp

• Instructions copy the https://github.com/coolmast/docker-fabric-web and change the Docker file inside the fabric folder

• open CLI in the fabric folder and run
  docker build -t coolmast/fabric .
  docker-compose up -d

-----Docker file------

ROM golang:latest

Can you try this again and let me know. Thanks.

[dbenji]

I deleted both container and image and rebuilt and compose it.

It seems to have the same issue

I like the dropdown menu and the possibility of changing the model

[ksylvan]

Okay, thanks. I'll take a look in the next couple of days.

[anddavros]

Of note, this may be unrelated. But in the CLI, (i haven't tried the web-interface), I'm getting a 'transcript not available' error regardless of model when using the youtube api.

[ksylvan]

Hmmm... Do you have yt-dlp installed?

From the README:

[anddavros]

I do, but haven't updated since last month, so that's likely the issue. I'll double check in the morning. Thank you!

[ksylvan]

That is the issue. It needs to be the 2025.06.09 version. Please verify when you can and we can close this issue.

[ksylvan]

Any update @anddavros ?

[alastair87]

I have version 2025.06.09 of yt-dlp installed with snap in Ubuntu 24.04 and I am still getting Transcript not available. (EOF). I thought it might be an issue with fabric not having /snap/bin in its path, but symlinking yt-dlp into /usr/bin didn't help. fabric version is v1.4.211. Technically should also mention that Ubuntu is running in WSL2 though I would be surprised if that matters.

[anddavros]

Any update @anddavros ?

Sorry for the delay, have been troubleshooting other issues. after a couple rounds of updates it looks like it's working, thank you. It was in part the versions I had been running. Hadn't updated in a while. Thank you. I have not yet tried the web interface, so I can't speak to it's function.

[ksylvan]

Ok. I closed the issue.

[dbenji]

hey @ksylvan why did you close the bug? the 2 issues were not related. On my test the yt-dlp via cli always worked on a native Windows install or via a Docker container using Linux. The issue with the Web interface still persists. It seems that the web interface interface is not able to fetch the youtube link and parsing it on fabric.
