This change breaks the CI workflow:

  make bin-***-dashboard-web
  shell: /usr/bin/bash -e {0}
  env:
    IMAGE_NAME: ***/***-dashboard-web
    BINARY_NAME: ***-dashboard-web
make: *** No rule to make target 'bin-***-dashboard-web'.  Stop.
Error: Process completed with exit code 2.

I'll send a PR to fix it.
