Repro Rate: 3/3

This issue was reproduced in //UE5/Release-5.1 at CL 23058290.

This is confirmed to not be a regression since the error also occurs on the previous live version. This is regression tested on //UE5/Release-5.0 at CL 20979098.

There seems to be something wrong with not finding any workers. Check the attached log for more details. Running the command only with a single "Automation RunTests Project" or "Automation RunFilter Smoke" works perfectly fine, the issue only occurs when combining the two in a single command.


Steps to Reproduce


  1. Open cmd in the Workspace/Engine/Binaries/Win64 directory.
  2. Run the following command:
    • UnrealEditor.Exe [Project.uproject] -ExecCmds="Automation RunTests Project, Automation RunFilter Smoke" -unattended -nopause -NullRHI -testexit="Automation Test Queue Empty" -log -log=RunTests.log
    • Replace [Project.uproject] with the path to the uproject file in quotations.

Actual Result: The Automation tool runs all Tests that match the "Project" Filter and then all tests that match the Smoke Filter and then exits.

Expected Result: The command is stuck in an endless loop and never starts any tests.
