Problem to generate crd with terraform object type

[littlejo]

What happened?

I have this error:

make generate

in terraform, ca is of type: object("crt": types.StringType,"key": types.StringType)

How can we reproduce it?

git clone https://github.com/littlejo/provider-cilium
cd provider-cilium
git checkout cilium-ca
make submodules
make generate
