Firebase iOS TestLab failed during validation: The XCTest zip file was malformed

Question

I have created iOS Lane for uploading Flutter integration tests to Firebase TestLab and it fails when trying to run the test. When I upload manually ios_tests.zip file which contains Runner_iphoneos folder and Release_iphoneos15.2-arm64.xctestrun, it pass on TestLab, but when using workflow .yml file in github action, TestLab fails to execute the tests.

Here is the error log for specific failing part:

Uploading [build/ios_integ/Build/Products/ios_tests.zip] to Firebase Test Lab...

Test [matrix-1aenoclku3vww] has been created in the Google Cloud.

Firebase Test Lab will execute your xctest test on 1 device(s).

Creating individual test executions...................failed.

ERROR: (gcloud.firebase.test.ios.run) 

Matrix [matrix-1aenoclku3vww] failed during validation: The XCTest zip file was malformed. The zip did not contain a single .xctestrun file and the contents of the DerivedData/Build/Products directory..

So the ios_tests.zip file is uploaded and I can find it in GCS bucket. When I extract it I can find all the files. But when I try to manually upload this file to TestLab it gives the same error. Seems like it is somehow changed in the build or upload process. Also it is strange that logs say that Matrix [matrix-1aenoclku3vww] is created, but I cannot see it in firebase console in TestLab. Like its not run at all.

This is the .yml script I use, it fails only at "Run Instrumentation Tests in Firebase Test Lab":
