I have a github workflow file where I’m using sed to replace variables within a configuration file, code below. The error i’m getting is with the GA_MP_SECRET line:

Run sed -i 's/${GA_MP_SECRET}/***/g' configs/myworkflow.yaml
sed: -e expression #1, char 53: unknown option to `s'

At first I thought the path being inserted with ${{ env.CONTAINER_APP_YAML }} might be causing an issue due to the slash, but the first three sed lines (under “Modify app yaml basics”) don’t cause an error.
The VERY weird part is that I tried moving consolidating all the sed lines from “Modify app yaml secrets” up underneath the ‘Modify app yaml basics’ sed lines, and suddenly the IMAGE_TAG sed line breaks. Same error. Yes, the line that didn’t cause an error before.

I figured there must be a hidden character or something breaking this, but I can’t track anything down. Any advice? I’ve been trying to fix this for four hours, and very frustrated!

The workflow file:

  build:
    runs-on: ubuntu-latest
    environment: dev
    env:
      CONTAINER_APP_NAME: software-api-test
      LOCATION: central_us

      ACR_NAME: softwareacr
      CONTAINER_APP_YAML: "configs/myworkflow.yaml"
    steps:
      - uses: actions/checkout@v2

      - name: Log into Azure
        uses: azure/login@v2
