Gitlab CI File Fails Linting

When I copy and paste the Go Gitlab CI template file in my project, my linter fails with the following error:

 This GitLab CI configuration is invalid: jobs dast environment deploy config should implement a script: or a trigger: keyword.

I have verified that DAST is turned off, and I created environment, dast, deploy, and config blocks, all having a script tag that simply reads, for example:

    - echo "Hello world"

I also tried naming the blocks something different but keeping the names as part of the stage:

  stage: dast
    - echo "Hello world"

No matter what I do, my CI file does not pass linting. Does anyone have insight into why this issue might be happening?

Thank you so much!
