Error: unable to create group with error: response status code was not 200

Group creation provider is broken:

Plan : Seems ok at first

base) welcome@Traianos-MacBook-Pro bitbucket-iac % terraform plan -out terraform.plan
bitbucket_project.example: Refreshing state... [id={e22a7ac4-0ea1-4fd6-9e51-be7f399f1b49}]

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  # bitbucket_group.orion will be created
  + resource "bitbucket_group" "orion" {
      + id         = (known after apply)
      + name       = "orion"
      + permission = "write"
      + slug       = (known after apply)
      + workspace  = "{engeneon}"
    }

Plan: 1 to add, 0 to change, 0 to destroy.

────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────

Saved the plan to: terraform.plan

To perform exactly these actions, run the following command to apply:
    terraform apply "terraform.plan"
.
