• Make sure the project opens
• runs with 0 errors
• a pattern can be added
• files are copied to output on build

Also the build is failing for some missing files, and bad configuration.

This warning appears:

Configuration key [debug] inside patternlab-config.json was found. As of Pattern Lab Node Core 3.0.0 this key is replaced with a new key, [logLevel]. This is a string with possible values ['debug', 'info', 'warning', 'error', 'quiet'].
Turning on 'info', 'warning', and 'error' levels by default, unless [logLevel] is present. If that is the case, [debug] has no effect.
