Error message

the inference provider rejected the request as invalid. Check the request body for unsupported or invalid fields

What it means

Sentinel error (llmerrors.ErrBadRequest) representing an HTTP 400 from the inference provider (e.g. Anthropic). It fires when the provider maps the provider's invalid_request_error type via NewProviderError, meaning the LLM request body contained unsupported or invalid fields rather than a client-side format problem. The Anthropic proxy compares provider errors against it with errors.Is to shape the API error response.
