What files are you installing? How does those look like?

> FILES_${PN} = “/*”

Here you add say that anything that has been installed, but not put into
any other package, should be added to ${PN}. Is that what you want?

> ALLOW_EMPTY_${PN} = “1”

Remove this one unless ${PN} is going to be empty.

> INSANE_SKIP_${PN} = “debug-files dev-so”

These might be needed if you get certain QA-warnings/error without them.

See answer below.

I assume that they aren't in the package you just created? Do you have
anything in your package that might have a dependency on the kernel
headers? Do you have anything in your IMAGE_FEATURES?

> Why are there .debug in the package folder, it should only be in package –dbg folder, right?

Where are the .debug directories located? You should add them to:
FILES_${PN}-dbg += "<location>/.debug"
