I’m setting up two workflows. One is supposed to run when I push to any branch other than main and the pushed code modifies something in the frontend subdirectory. Similarly, the other is supposed to run when I push to any branch other than main and the code modifies something in the backend subdirectory.

The .yml file for the frontend workflow looks like this:

name: frontend-push
Controls when the action will run.
on:
Triggers the workflow on pushes to any branch
push:

branches:

- '!main'

paths:

- 'frontend/**'
Allows you to run this workflow manually from the Actions tab
workflow_dispatch:
A workflow run is made up of one or more jobs that can run sequentially or in parallel
jobs:
This workflow contains two jobs: one called build and one called test
build:

# The type of runner that the job will run on

runs-on: ubuntu-latest
# Sets default working directory for all steps in job
defaults:
  run:
    working-directory: frontend

# Test multiple versions of node
strategy:
  matrix:
    node-version: [12.x]


# Steps represent a sequence of tasks that will be executed as part of the job
steps:
  # Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it
  - uses: actions/checkout@v2
  # Configure the specified Node.js version on the runner
  - name: Use Node.js ${{ matrix.node-version }}
    uses: actions/setup-node@v1
    with:
      node-version: ${{ matrix.node-version }}
  - run: ls -la
  - run: echo $PWD
  - run: npm install   # install the package and packages it depends on
  - run: npm run build --if-present   # creates a production build
  - run: npm test

I’ve tried testing this by creating a .txt file in the frontend directory and pushing the new file to a branch called test_github_actions, but the push did not trigger my workflow. I’ve been iterating on my workflow file for a while, and I’ve found and corrected (I think) a couple of errors, but I’ve gotten stuck here.

Is there an obvious issue with my .yml file?
