TL;DR

The API error 529 overloaded suggests that the system is experiencing high load, and a workaround may involve reducing the load or waiting for the system to recover.

Guidance

• The error messages indicate a lock acquisition failure and a marketplace file not found error, which may be related to the overloaded error.
• The overloaded_error message suggests that the system is experiencing high traffic or load, and the request cannot be processed at this time.
• To mitigate this issue, try reducing the load on the system or waiting for a short period before retrying the request.
• Verify the system's load and resource utilization to determine if it is indeed overloaded and if there are any other errors or issues contributing to the problem.

Notes

The provided information does not specify the exact cause of the overload or how to permanently resolve the issue. Further investigation into the system's resource utilization and load handling may be necessary to determine a long-term solution.

Recommendation

Apply workaround: wait for a short period before retrying the request, as the system may recover from the overload.
