Github action No event triggers defined in `on`

Question

I have created a pipeline and i want to trigger every time I push on any branch

There is my default.yml :

name: default

on:
  push:
    branches:
    - '*'

jobs:
  build:
    runs-on: macOS-latest
    
    steps:
    - uses: actions/checkout@v1
    - name: CocoaPod Install
      run: pod install
    - name: Force xcode version
      run: sudo xcode-select -switch /Applications/Xcode_11.2.1.app
    - name: Build
      run: ./pipelines.sh build

When i push this on github, I have this error

No event triggers defined in on

You can trigger all branches just by using

on: push

https://docs.github.com/en/actions/reference/events-that-trigger-workflows#example-using-a-single-event

Remove - '*'

Your workflow file seems fine. Have you checked all indentation.

For what it's worth, I'm not sure what causes this error either. It seems to be some combination of syntax or parsing error covered up by a less useful error.

For me,

checking whitespace
making sure there was a line-break between a comment block and the events block
switching from paths to paths-ignore

One of those things fixed it for me.

I got this error from a commit where I have only edited the workflow yaml file but nothing else. It was triggered normally after editing and commiting other files.
