Hi @Sander0542, any news on terraform release containing this patch ?

[Sander0542]

This PR needs to be merged before I can patch the Terraform provider

One question: Why exactly? I can infer that there are improvements (and fixes) I just want to know what lead you to want to make this contribution

In future, any PR with an empty description will be immediately closed.

I created this PR to improve the OpenAPI schema. Currently it is not matching the actual API definition, so that makes it hard to generate ready to use HTTP clients.

I will be sure to add a PR description the next time :)
