Can PR decoration work with old sub-modules setup?

PR decoration will stop working as soon as we set sub-modules in sonar properties with sonar.modules key
So my question is: Is PR decoration compatible with “old” sub-modules setup?

  • No error in analysis logs
  • No error in background tasks
  • SonarQube EE 7.9
  • GitHub Enterprise 2.17.5

I don’t see why pull request decoration wouldn’t be compatible with any scanner configuration, including the old sub-modules setup.
Do you see issues in SonarQube for that P/R that should be decorated in GitHub? Have you tried setting logs to DEBUG in SonarQube (specifically for the Compute Engine)?
