    update to the following, but can’t help much further without full context of structure

    COPY ./package.json ./

    The local build and the pipeline build are launching from different paths, but both are provided with the same . relative build context, which means they resolve to different paths.

    To emulate the local build, supply the equivalent "build context" paramater

    docker build -t $CI_DOCKER_REPO:$CI_COMMIT_SHORT_SHA 
  -f ./cronTest/Dockerfile 
  ./crontTest

    Or move into the same directory

    cd cronTest
docker build -t $CI_DOCKER_REPO:$CI_COMMIT_SHORT_SHA 
  -f Dockerfile 
  .
