If you're encountering an unexpected parse error while running a Godot workflow in GitHub Actions, it typically indicates an issue with the YAML syntax or configuration in your workflow file. Here's how you can troubleshoot and fix the error:

Steps to Resolve GitHub Actions Parse Error:

1. Check YAML Syntax:

   • YAML is sensitive to indentation, so ensure that all indentations are consistent (use spaces, not tabs).

   • Use an online YAML validator to check for any syntax issues.

   • Example of correct indentation:

     jobs:
       build:
         runs-on: ubuntu-latest
         steps:
           - name: Checkout repository
             uses: actions/checkout@v2
           - name: Set up Godot
             uses: godotengine/action-godot-build@v1
             with:
               godot-version: '3.4'
           - name: Build Godot Project
             run: godot --export "Linux/X11" ./project.godot
     
     

2. Ensure Correct Godot Action Version:

   • Verify that you're using the correct version of the Godot action. For example, check if godotengine/action-godot-build@v1 is compatible with your project.

   • If using a custom action, check that it's correctly configured.

3. Environment Variables:

   • Ensure all environment variables, like paths and Godot versions, are set correctly.

   • If you are using a specific version of Godot, ensure that version is available in your action configuration.

4. Check for Missing Fields:

   • Ensure that all required fields in the workflow are properly defined. GitHub Actions may throw a parse error if mandatory fields are missing.

5. Action Compatibility:

   • Ensure the Godot Action you're using is compatible with your version of GitHub Actions.

   • If you’re using a custom action, verify its documentation to ensure you're using it correctly.

Example Godot GitHub Actions Workflow:

name: Godot Build

on:
  push:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout Repository
        uses: actions/checkout@v2

      - name: Set up Godot
        uses: godotengine/action-godot-build@v1
        with:
          godot-version: '3.4'

      - name: Build Godot Project
        run: godot --export "Linux/X11" ./project.godot

Debugging Tips:

• Verbose Logging: Add set -x at the beginning of your shell commands to enable verbose logging for debugging.

• Check GitHub Actions Logs: Go through the logs carefully to identify where the error occurs. It can often point to the exact line where the syntax or logic is wrong.

Let me know if the error persists, and I can help troubleshoot further!
