error with txt2vid example in docs

[detain]

When trying the txt2vid example in the docs it gives this message in the logs and fails to work.

argh, yes. I'm aware that diffusers changed quite few things in the meantime regarding video generation. I'm looking into adding newer models and recently added specific endpoint for video generation #5247, next releases will show a bit more love into that direction
