Queue callback error: Error [MessageNotFoundError]: Message id not found

On Vercel World I have a workflow that failed a bunch of times because of a 429 from a service I use.

I tried replaying them to get a successful completion, and I managed that. But then I saw a bunch of 500 responses for this request POST /.well-known/workflow/v1/flow saying:
