A common issue in multi-step AI workflows involves retry logic that fails after provider migrations due to differing error code vocabularies. Workflows designed for one provider's error statuses, such as 429 for rate limiting, may either become dead code or enter infinite loops when encountering a new provider's distinct error codes (e.g., Anthropic's 529 for overloaded errors or OpenAI's 429 for both rate limiting and spend limits). Additionally, streamed responses can present errors within a successful HTTP 200 status, making them difficult to diagnose as they appear as partial output without explicit logging. AI
