Building Angular Project fails without any error logs

We have a simple CI/CD pipeline which should build the Angular project and copy everything to another folder. The pipeline fails for no apparent reason.

Here’s our .gitlab-ci.yml

build_fe:
  stage: build
  only:
    refs:
      - dev
  script:
    - mkdir test
    - cd Frontend
    - npm i
    - npm run build:test
    - cp -r ./dist/projectname/* /var/www/test.domain.com/html
  tags:
    - test

And here are the logs (raw output):

When doing all of this manually on the machine it works flawlessly and IIRC it has worked in the past.

Does anyone know what’s going on?

Hi @T0Bii
since you are running Shell executor it could be also cause by any change on the server where GitLab runner is running.
Any change on the server recently? Like upgrades or similar.
