Ungraceful failure error when the anthropic api is overloaded

[Nick Sullivan]

Description

When anthropic api is busy/down, it responds with

{"type":"error","error":{"details":null,"type":"overloaded_error","message":"Overloaded"}}

Which causes an unhandled rejection

unhandledRejection: TypeValidationError [AI_TypeValidationError]: Type validation failed: Value: {"type":"error","error":{"details":null,"type":"overloaded_error","message":"Overloaded"}}.
