error::Cannot read property 'startsWith' of undefined

G’day:

I am testing this action locally with act like so:

act -j deployToFirebase -v

My stack:

• macOS Catalina
• node v14.3.0
• yarn 1.22.5
• act 0.2.14

I am running into a problem, and here’s the partial stack trace:

[Build and Deploy to Firebase/deployToFirebase] Exec command '[node /actions/dorny-paths-filter@v2/dist/index.js]'
[Build and Deploy to Firebase/deployToFirebase]   ❗  ::error::Cannot read property 'startsWith' of undefined
[Build and Deploy to Firebase/deployToFirebase]   ❌  Failure - dorny/paths-filter@v2
...
DEBU[0040] exit with `FAILURE`: 1
DEBU[0040] exit with `FAILURE`: 1
DEBU[0040] exit with `FAILURE`: 1
Error: exit with `FAILURE`: 1

My workflow file deployToFirebase.yml looks like:

name: Build and Deploy to Firebase

on:
  push:
    branches: [ develop ]

jobs:
  deployToFirebase:

    runs-on: ubuntu-latest
    env:
      CI: ""

    steps:
    - name: Check out code
      uses: actions/checkout@master
    - uses: dorny/paths-filter@v2
      id: filter
      with:
        filters: |
          frontend:
            - 'src/**'
          backend:
            - 'functions/**'

     # run only if 'frontend' (hosting) files were changed
    - name: frontend steps
      if: steps.filter.outputs.frontend == 'true'
      run: |
        echo "<<<<<<<<<<<<<<<<<<<<<<< frontend changed"
     # run only if 'backend' (functions) files were changed
    - name: functions steps
      if: steps.filter.outputs.backend == 'true'
      run: |
        echo ">>>>>>>>>>>>>>>>>>>>>>> functions changed"

What am I not doing right? Or is there anything special I have to do in order to use this action?

I am also open to suggestions on how else to test locally to save on the hassle of first sending the code to github and then waiting for the workflow result

Image needs to be pulled just once. You can do it independently from act: docker pull nektos/act-environments-ubuntu:18.04. Image size shouldn’t affect container startup time, so once you have it locally only remaining issue is it will take 18GB from your disk drive.

Alternative would be to build your own custom image based on the act default image, but with git installed. If you decide for this solution, you should be sure it’s actually worth the effort 😃

Building custom image for act is quite out of scope of this project (and my knowledge) so if you will need some support the act repository is probably a better place.

Trying to do the same thing, it looks like the “medium” container now contains git but runs into a problem with github not being a part of the known hosts, PR Ref, Issue ref that they’re working on.
