GitHub actions currently has degraded status. The PR looks good but it shouldn't be merged before integration test

[Ileriayo]

Integration tests look fine to me.

Right?

[melihc1]

Yes, it looks fine. Action didn't start right after we merged changes to integration branch yesterday. I'm merging this PR now.
