YAML is strict

If you’ve never written YAML before, one common issue, and one that I ran into myself making this blog, is using tabs rather than spaces 🤯

❌ This doesn’t work:

foo:
	bar: baz

☑️ This does work:

foo:
  bar: baz

You can barely spot the difference, so it’s easy to get stuck on thinking something else is causing an issue.
