Hi @madiganz , 

I guess this *** is caused by masked values. Do you use any secrets variables in your workflow which value macthes the masked string in file name before _ builder ? 

For example, if you have a secret variable names ‘env’ which value is ‘product’ ,

and in your workflow you used secrets env in an step environment variable. 

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: print secrets
      run: |
         echo 'product_build'
      env:
        ENV: ${{secrets.env}}

Then in workflow run logs, all the string “product” will be insteaded by “***”

Or do you use add-mask command ? 

If this could not match your scenario, could you please tell me your complete file name?
