TL;DR

The most likely fix is to reduce the load on the API to prevent "overloaded" errors.

Guidance

• Verify the API usage patterns to identify potential causes of overload, such as excessive requests or large payload sizes.
• Consider implementing rate limiting or batching requests to reduce the load on the API.
• Check the API documentation for any specific guidelines on handling overload errors or recommended usage patterns.
• Monitor the API error logs to detect any recurring overload errors and adjust the usage patterns accordingly.

Notes

The provided error messages indicate an "overloaded" error, suggesting that the API is unable to handle the current load. Without more information on the API usage patterns or the specific requirements of the API, it's difficult to provide a more detailed solution.

Recommendation

Apply a workaround by reducing the load on the API, such as implementing rate limiting or batching requests, to prevent "overloaded" errors. This approach can help mitigate the issue until a more permanent solution is found.
