How can I debug a YAML error in my configuration file?

I'm getting a parsing error in my YAML file. How can I debug it?

First, check for common issues like incorrect indentation, missing colons, or unquoted strings. Can you share the error message?

The error says 'mapping values are not allowed here'. What does that mean?

This usually indicates that there's a syntax issue, like a missing key or an extra space. Can you show me the relevant part of your YAML?

Sure, here it is:

server:
  host: localhost
  port: 8080
  endpoints:
    - path: /api
      method: GET
      handler: apiHandler
  
  - path: /health
    method: GET
    handler: healthHandler

I see the problem! The second endpoint is incorrectly indented. It should align with the first endpoint. Try this:

server:
  host: localhost
  port: 8080
  endpoints:
    - path: /api
      method: GET
      handler: apiHandler
    - path: /health
      method: GET
      handler: healthHandler
