When Anthropic returns HTTP 529 (overloaded), the user-facing error message says:

TL;DR

Update the isOverloadedErrorMessage() branch in agent-runner-execution.ts to return a distinct error message for HTTP 529 errors.

Guidance

• Identify the isOverloadedErrorMessage() function in agent-runner-execution.ts and update its return statement to reflect the expected behavior for 529 errors.
• Verify that the updated function correctly handles both 429 and 529 error codes by testing with simulated API responses.
• Consider adding logging or monitoring to track instances of 529 errors to better understand the frequency and impact of temporary overloads.
• Review the user-facing error messages to ensure consistency and clarity in communicating different types of errors.

Example

// In agent-runner-execution.ts
function isOverloadedErrorMessage(errorCode: number): string {
  if (errorCode === 529) {
    return "The AI service is temporarily overloaded. Please try again in a moment.";
  }
  // ...
}

Notes

This fix assumes that the isOverloadedErrorMessage() function is the sole source of the misleading error message. Additional review of related code and error handling mechanisms may be necessary to ensure a comprehensive solution.

Recommendation

Apply workaround: Update the isOverloadedErrorMessage() function to return a distinct error message for 529 errors, as this directly addresses the root cause of the misleading user-facing error message.
