terraform-provider-huaweicloud: "huaweicloud_cce_cluster_v3" resources and data always return "Action Forbidden" even with Full Privilges

Description

I’m trying to create a CCE cluster in region cn-south-1. I am an admin on the entire account, I have full privileges and am able to create a CCE cluster from the UI. However when trying to create a CCE cluster through Terraform or even retrieve an existing CCE cluster, I get the following error: data Error: Unable to retrieve clusters: Action Forbidden resource Error: Error creating HuaweiCloud Cluster: Action Forbidden

When trying to do the same action in a different region - ap-southeast-1 everything works.

Debug info
