I think we should define how we will use labels in the project.
See the current list here: https://github.com/OpenAPITools/openapi-generator/issues/labels

What is the difference between bug and invalid ?

Is invalid for an issue that is not correct?

I also think we need to do the difference between something broken in the generator (for example a NullPointer when we run the code) and something that is wrong in the generated code (that is often only for a specific OpenAPI sepecification, and for one target language)

I also think we need a discussion type of issue.
