I have seen "You must specify at least one target queue to send a job to helix. Use the HelixTargetQueues property or HelixTargetQueue items." error in some jobs, e.g. https://github.com/dotnet/runtime/pull/98858/checks?check_run_id=22732088742

Is this related?

Looking at the error, that looks like more of a problem with specifying helix target queues. That would be more indicitive of a missing helixQueuesTemplate: argument to the platform-matrix template than the issue that this PR is fixing.

LGTM

@jkoritzinsky Looks like there's still a problem with the Helix correlation payload:

C:\h\w\9782089C\w\97C508A0\e>"C:\h\w\9782089C\p\dotnet.exe" exec --runtimeconfig Common.Tests.runtimeconfig.json --depsfile Common.Tests.deps.json xunit.console.dll Common.Tests.dll -xml testResults.xml -nologo -nocolor -notrait category=IgnoreForCI -notrait category=OuterLoop -notrait category=failing  
'"C:\h\w\9782089C\p\dotnet.exe"' is not recognized as an internal or external command,
operable program or batch file.

(Not sure why the jobs aren't showing up in the "Checks" list above)
