[Object Storage] Data Source for stackit_object_storage_credential shows credential could not be found

Hi :-)

I am currently trying to create our new STACKIT project through terraform. I created a storage bucket, a credential group and inside it some credentials.

Now I want to retrieve this information through the Data Source. But I always get a "Error: couldn't find credential". Not sure what I am doing wrong, maybe someone can assist me.

resource "stackit_object_storage_project" "terraform-state" {
  project_id = var.project_id
}

resource "stackit_object_storage_bucket" "terraform-state" {
  object_storage_project_id = var.project_id
  name                      = "terraform-state-bucket"
}

resource "stackit_object_storage_credentials_group" "terraform-state-cg" {
  object_storage_project_id = var.project_id
  name                      = "terraform-state-cg"
}

resource "stackit_object_storage_credential" "terraform-state-c" {
  object_storage_project_id = var.project_id
  credentials_group_id      = stackit_object_storage_credentials_group.terraform-state-cg.id
}

data "stackit_object_storage_credential" "terraform-state-bucket-credential-output" {
  object_storage_project_id = var.project_id
  display_name              = stackit_object_storage_credential.terraform-state-c.display_name
}

output "terraform-bucket-credential-information" {
  value = data.stackit_object_storage_credential.terraform-state-bucket-credential-output
}

Plan output shows

You can apply this plan to save these new output values to the Terraform state, without changing any real infrastructure.
