Cluster creation fails with cryptic error message

[baurmatt]

Hey,

I've tried to create a cluster on MetaKube and it failed with a cryptic error message:

Error: unable to create cluster for project 'jq6bhg998s': {"Op":"Post","URL":"https://metakube.syseleven.de/api/v1/projects/jq6bhg998s/dc/bki1/clusters","Err":{}}

Terraform Code:

provider "kubermatic" {
  host = "https://metakube.syseleven.de/"
}
resource "kubermatic_project" "project" {
  name = "mysql-test"
}

resource "kubermatic_cluster" "cluster" {
  dc_name = "syseleven-dbl1"
  project_id = kubermatic_project.project.id
  name = "no-name"

  spec {
    version = "1.17.9"
    cloud {
      openstack {
        tenant = "max-super-tenant"
        username = "john.doe@example.org"
        password = "password1234"
        floating_ip_pool = "ext-net"
      }
    }
  }
}

resource "kubermatic_node_deployment" "node_deployment" {
  cluster_id = kubermatic_cluster.cluster.id
  name = "no-name"
  spec {
    replicas = 3
    template {
      cloud {
        openstack {
          flavor = "l1c.medium"
          image = "Ubuntu Bionic 18.04 (2020-09-17)"
        }
      }
      operating_system {
        ubuntu {}
      }
    }
  }
}
