The build from another repository does not work.

I have two projects:
devops/deploy/landing and frontend/landing.

The gitlab-ci.yml file is stored in devops/deploy/landing, and everything works fine there.

But when I add this file to the CI frontend/landing settings the external gitlab-ci.yml: .gitlab-ci.yml@devops/deploy/landing build process starts, but it writes that there are no available runners, although the same runner as for devops/deploy/landing is added to frontend/landing.

I can’t understand what the problem is?
