• You have a string in your wurst.build that's malformed, for example:

buildMapData:
  name: 'My mate's map'

Expected Behaviour

The error should be mapped/pretty-printed to the user

Workaround

Don't write bad yaml

[Frotty]

I consider this fixed since we now ship the YAML plugin, which provides some validation.
Your example errors in vscode.
