Better error messages for generators when failing to write to catalog.

[boyney123]

Use Case

When the generator tries to write a value that is undefined to the catalog, the YML module under the hood will give error messages like this

Processing 1 AsyncAPI files...
Processing C:\Users\ivangsa\workspace\EDALearn\EDA-Playground-Online-Food-Delivery\modules\orders\src\main\resources\apis\asyncapi.yml

Processing domain: Orders (v0.0.1)
 - Domain (v0.0.1) created
Error loading plugin: YAMLException: unacceptable kind of an object to dump [object Undefined]
    at writeNode (C:\Users\ivangsa\workspace\EDALearn\EDA-Playground-Online-Food-Delivery\event-catalog\node_modules\gray-matter\node_modules\js-yaml\lib\js-yaml\dumper.js:779:13)
....
}

It would be more useful to give error message that make more sense.
