AttributeError: 'Room' object has no attribute 'local_participant'

Suddenly getting this error when using livekit agents playground. Checked KITT and it too is not connecting, though I can't see the logs there. Maybe it's a problem with the playground side since it previously worked ok with my installed package versions and suddenly stopped working.

more context: can't be a playground issue afaik. I also set up local playground and it looks like last commit was >1 week ago.

must be something on the livekit cloud side

@willsmanley I think you are missing the explicit connect that's required in the latest version. see the example here for details.

the kitt demo is due to another issue. we are in the process of updating the examples and looks like there was a problem in that deployment.

yep that fixed it! must have missed that with the new release. thanks again!
