The CRD contains

              license:
                description: License information is required.
                properties:
                  accept:
                    description: The license must be accepted 
                    enum:
                    - true
                    type: boolean

Hi @fmhwong , that's fair, thanks for taking the time to file this issue.
Should be fixed in #6933 👍

@andreaTP Thanks for the quick turnaround!

It was a good excuse to verify that I still remember something about the codebase 😅
