extent analysis

TL;DR

The ultrareview API error is likely due to an overloaded server, and a workaround may involve retrying the request or checking the API's load.

Guidance

  • The error message "Overloaded" suggests that the server is currently handling too many requests, so waiting and retrying the request might resolve the issue.
  • The "Request was aborted" error could be related to a timeout or connection issue, which might be mitigated by adjusting the request timeout or checking the network connection.
  • To verify the issue, check the API's status page or documentation for any known issues or load limits.
  • Consider implementing a retry mechanism with a backoff strategy to handle temporary overload errors.

Example

No code example is provided as the issue does not contain sufficient information about the implementation.

Notes

The provided information does not specify the exact cause of the overload or the aborted request, so further investigation into the API's documentation and server status is necessary.

Recommendation

Apply workaround: Implement a retry mechanism with a backoff strategy to handle temporary overload errors, as the issue seems to be related to server overload rather than a version-specific bug.
