TL;DR

The issue is likely due to exceeding the payload size limit, and reducing the payload size or increasing the limit may resolve the "413 Payload Too Large" error.

Guidance

  • Verify the current payload size being sent and check if it exceeds the expected limit.
  • Consider reducing the payload size by optimizing the data being sent or splitting it into smaller chunks.
  • If possible, check the OpenAI API documentation for any guidelines on increasing the payload size limit.
  • Review the error handling mechanism to ensure it properly catches and handles the "413 Payload Too Large" error.

Notes

The provided information lacks specific details about the payload size and the OpenAI API being used, making it challenging to provide a more precise solution.

Recommendation

Apply workaround: Reduce the payload size to avoid exceeding the limit, as this is the most direct approach to resolving the "413 Payload Too Large" error without requiring additional information about the API or its configuration.
