When try to use haiku-20241022 through librechat, I get this error: Something went wrong. Here's the specific error message we encountered: Operation failed after 3 attempts: 400 {"type":"error","error":{"type":"invalid_request_error","message":"prompt: Input should be a valid string"}}.

With the same API key and other settings remaining default, everything works fine when using sonnet-20241022 through librechat.

With the same API key, using haiku-20241022 through chatbox also works normally.
