Error message

{message} (code: {typ})

What it means

Fallback branch in catch_error: the non-2xx JSON body has an error object with a 'code' string (e.g. 'context_length_exceeded', 'invalid_api_key') instead of a 'type' field — the Anthropic/OpenAI variant of the error envelope. The message is the provider's human-readable description; the code classifies it. Only reached when the 'type' field was absent.

Solutions

1. Match known string codes (e.g. context_length_exceeded) to user-facing guidance such as trimming the conversation or starting a new session
2. Retry transient server-side codes with backoff
3. Treat credential-related codes as fatal and prompt re-authentication rather than retrying

When it happens
