500 Error when checking for logs of pending solver

[mayaCostantini]

Describe the bug

Environment: stage

Checking for logs of a pending solver job gives an InternalServerError:

{
  "details": {
    "datetime": "2022-09-13T12:41:39.258229",
    "type": "InternalServerError"
  },
  "error": "Internal server error occurred, please contact administrator with provided details."
}

When solver status is pending:

{
  "parameters": {
    "analysis_id": "solver-rhel-8-py38-220913123942-1a7a720b5e604db4"
  },
  "status": {
    "finished_at": null,
    "reason": null,
    "started_at": null,
    "state": "pending"
  }
}

To Reproduce

Go to the stage instance of Management API and try to solve a package, then check for solver logs when status is pending. Package used to observe this error was:

{
  "package_name": "fext",
  "version_specifier": "*"
}

from https://pypi.org/simple.

Expected behavior This should be handled as a 400 error.
