GA-S003: Type mismatch

Error Schema

Why This Matters

A value in the workflow file has the wrong type. For example, `runs-on` expects a string or array but received a number, or `timeout-minutes` expects a number but received a string. Type mismatches cause GitHub Actions to reject the workflow at parse time.

How to Fix

Change the value to the correct type expected by the schema.

Before (incorrect)

jobs:
  build:
    runs-on: 42
    steps:
      - run: echo hello

After (correct)

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - run: echo hello
