pulling docker image for 20+ minutes in pipeline

I am trying to use a public docker image in a pipeline. Its size is only 500M but the pipeline stuck at the pulling images step for 20+ minutes and eventually times out. There is no log on the web interface. Can someone help me understand which part went wrong?

  - step:
      name: Test end-to-end via nightwatch
      image: tjlian616/nightwatch_chrome
      caches:
        - node
      script:
        - npm install
        - npm run nightwatchCI
