generating typescript models fails for specific space with TypeError: contentTypeValidation.linkContentType.map is not a function

[TijmenH]

It seems there's an issue with our contentful space that causes the codegen to break. We tried running the codegen in a new organization and it worked perfectly. However trying to generate models on our existing environment throws the following error:

yarn run v1.22.19
$ contentful-typescript-codegen --output types/generated/contentful.d.ts

I assume the problem is with one of our content models but as we have a lot we're not sure how to find out which content type is causing this exactly.

Is there any way we can investigate this or find out where the problem comes from?
