CDKTF convert: Internal Error: unexpected array

[scraly]

Expected Behavior

$ echo 'resource "ovh_cloud_project_kube" "my_kube_cluster" {
  name         = "my_kube_cluster_cdktf"
  region       = "GRA7"
}' | cdktf convert --language go --provider 'ovh/ovh'

--> providing the Go file with the code generated according to the OVH provider (https://registry.terraform.io/providers/ovh/ovh/latest)

Actual Behavior

Executing the covert command cause an error: Internal Error: unexpected array

$ echo 'resource "ovh_cloud_project_kube" "my_kube_cluster" {
  name         = "my_kube_cluster_cdktf"
  region       = "GRA7"
}' | cdktf convert --language go --provider 'ovh/ovh'

Any word on this? 3111 has been closed. 3170 waiting on answer status was removed by bot which seems like an inappropriate action setting. I am seeing this same issue on conversion to python. If anyone knows a combination of cdktf and node versions that work, please advise.

I am unsure why this is happening yet.

The core reason for the (unhelpful, I must add) error is that the provider schema that we're trying to convert seems to be wrong. For each list or set attribute type, it should be an array with two elements, the first one informing us whether it's a set or a list, and the second is the value type. In the above case, we're getting four elements, which are basically two elements duplicated again.

I tried to chase down where this is coming from, but it isn't clear yet. I'll continue to investigate this.
