Hi everybody,
I have some automation tests I wish to execute in a packaged game using a CI workflow.
So I have setup Gauntlet to start the test after packaging the game.
I am using the command .uat RunUnreal -- -build=local -Test="UE.TargetAutomation" -RunTest="My.Awesome.Test" to start Gauntlet testing. This starts the packaged game, as well as the editor, without any issues.
The game log shows me that it detects all my own automation tests as well as engine internal tests just fine:
[2025.06.18-14.11.51:707][868]LogAutomationCommandLine: Display: Found 1335 Automation Tests
[2025.06.18-14.11.51:707][868]LogAutomationCommandLine: Display: 'My.Awesome.Test'
....
However the editor gets stuck while trying to communicate with the game. It tells me that it cannot find any workers:

Because of this, Gauntlet gets stuck and aborts after 300 seconds.
I am testing everything on my local machine on Windows (no CI involved yet). Do I have to do any setup for the project to make Gauntlet work? Or am I missing something with the command I am using?
Any help is much appreciated, thank you.
