Github actions syntax: Invalid workflow file-CodePudding

I started using github actions and I am trying to let a few lines of shell script running before I create a python package. But I can't get my code to run. It always stops on the line run: | - which is odd because I have been using this exact line before before (see further down). Does anyone know what I am doing wrong?

name: Python packaging

on: [push]

jobs:
    job1:
        name: Update version
        runs-on: ubuntu-latest
        steps:
            - name: checkout repo
               uses: actions/checkout@v3

               # ----- This is where the error occurs. Error message: 
               # Check failure on line 11 in .github/workflows/main.yml 
               # GitHub Actions / .github/workflows/main.yml
               # Invalid workflow file 
               # You have an error in your yaml syntax on line 11

            - name: Increase version
               run: |
               old_version=$(grep -oP '(?<=0.0.)[0-99] ' contrib/_version.py)
               new_version=$(($old_version   1))
               str="__version__=\"0.0."
               out="$str$new_version\""
               sed -i '1s/.*/'$out'/' contrib/_version.py

     job2:
        name: Build and upload
        needs: job1
        runs-on: ubuntu-latest
        strategy:
          matrix:

CodePudding user response：

The file is in YAML syntax which highly depends on indentation.

Based on your example:

job1: and job2: must be at the same column.
Under steps:, name: and uses: must be at the same column.
