GITHUB ACTIONS replace character in string

Question

I'm trying to replace a character in a variable within a GITHUB actions step

  - name: Set Up DB Name
    run: |
      DB_NAME="${GITHUB_REF_SLUG/-/_}"
      echo $DB_NAME

I'm getting a bad request error

What am I doing wrong?

Answer 1

I successfully made the character replace works (with GITHUB_REPOSITORY) using this implementation:

job1:
  runs-on: ubuntu-latest
  steps:
    - name: character-replacement-test
      run: |
        REPO=$GITHUB_REPOSITORY
        DB_NAME="${REPO//-/_}"
        echo $DB_NAME

I couldn't get to the same result with 2 lines. (But someone more experienced with bash might help us get there as well).

Evidence:

So in your case, it should work using this code if you substitute the GITHUB_REPOSITORY by GITHUB_REF_SLUG in your workflow.
