Hi @full merlin, I also get this error occasionally. I had it a few weeks ago as well. Not sure anymore what caused it to start working again then.
The issue seems to be a bit random; once the Convex CLI is in this state it isn't resolved by switching to a stable branch (e.g. main) and rerunning convex dev. It also doesn't seem to recover on its own; it stays in an InternalServerError loop indefinitely:

Think I'll be able to resolve this by clearing cache or creating a new dev deployment, but would appreciate help with this
