Piggybacking on this, though I'm getting a different error with Forge (latest version as of this comment):

Agent Scheduler needs to be updated to work with v2 of the pydantic library. That is the root of all these errors. Hopefully the author can address this because it requires a thorough rewrite. Downgrading to v1 of pydantic (quite old by now) is not a workable fix for most people.
