`executable` in Run Action not setting properly

I have configuration with other app added to project byprojectReferences

projectReferences:
  xyz:
    path: ../Modules/xyz/xyz.xcodeproj

and I set

schemes:
  xyz:
    build:
      targets:
        xyz/xyz: all
    run:
      executable: "xyz/xyz"

According to the documentation:

 executable: "xyz"

or

 executable: "xyz.app"

Not working too

And in project I have settings like this after xcodegen generate

Executable is missing 👎 How can I add this properly?

Start by reproducing the shown projectReferences and schemes configuration, then run xcodegen generate and inspect the generated Xcode scheme settings shown in the report. Compare the executable values xyz/xyz, xyz, and xyz.app; done when the generated project assigns the intended executable for the referenced target.
