Bug: demo/gemini_audio_video/app.py gradio webpage shows Illegal header value b'Bearer '

[ahundt]

I was trying to finish up #88 and I started out by running the current functionality on the main branch (not the pull request's code):

demo/gemini_audio_video/app.py launches, but when I try to hit record on the video I get the following popup in the web ui (nothing prints to terminal):

Illegal header value b'Bearer '

It looks like it might relate to this line:

fastrtc/backend/fastrtc/credentials.py

Line 54 in a6a0937

"Authorization": f"Bearer {token}",

as that's the only instance of Bearer in fastrtc itself.

I already ruled out alternative causes like the gemini api key which is working. I think this is likely a fastrtc bug, but I'm not sure. Thanks for giving this a look.

Hi @ahundt ! Yea instead of using twilio for the TURN server, I am using cloudflare through a hugging face token. It's free if you have a hugging face account. You can just delete all mentions of get_hf_turn_credentials from the gemini script though if you're running locally.

I think that fixes your issue so I will close.
