Job config should be a hash error

I getting following error job: .script config should be a hash. I have in my ci-yml created script template like this

.script: &build_script
  - cp config/ca.cnf.default config/ca.cnf
  - cp config/intermediate.cnf.default config/intermediate.cnf
  - cp config/encrypt.yml.default config/encrypt.yml
  - cp README.md README.txt

But passing build was 25 days ago, YML config script wasn't changed. Any ideas?
