      Name of Failure:

      Task run-performance-tests on build variant performance-tests (Evergreen project django-mongodb-backend). No failing tests: the failure is the post-task command attach.xunit_results.

      Context of when and why the failure occurred:

      New regression, first seen 2026-10-29; the daily performance signal has been red since. Every benchmark run passes and its results reach the dashboard, yet the post-task results upload marks the task system-failed.

      Last passing run: revision c588aec87f, 2026-10-29 00:15 UTC. First failing run: revision 931314c733, 2026-10-29 19:31 UTC. All 3 activated runs since fail identically; the 12 activated runs before that passed. Suspected change: INTPYTHON-1158.

      Stack trace:

      Command 'attach.xunit_results' in function 'upload test results' (step 1 of 3) in block 'post' failed: Files parameter was provided but no XML files matched.
Running post-task commands failed: running command: command failed: Files parameter was provided but no XML files matched
Post task completed - FAILURE. Overall task status changed to FAILED.
