terraform-provider-kustomization: Import errors out with "ResourceExists: unexpected end of JSON input"

As the title says. Any form of import for existing resources errors out with these lines:

kustomization_resource.argocd["~G_v1_Service|argocd|argocd-server"]: Importing from ID "~G_v1_Service|argocd|argocd-server"...
kustomization_resource.argocd["~G_v1_Service|argocd|argocd-server"]: Import prepared!
  Prepared kustomization_resource for import
kustomization_resource.argocd["~G_v1_Service|argocd|argocd-server"]: Refreshing state... [id=8a695083-93f5-492f-92ec-959680e9db61]

Error: ResourceExists: unexpected end of JSON input

The id 8a695083-93f5-492f-92ec-959680e9db61 does match with the existing service in this case.

The rendered json in plan mode looks correct as far as I can tell:

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  # kustomization_resource.argocd["~G_v1_Service|argocd|argocd-server"] will be created
  + resource "kustomization_resource" "argocd" {
      + id       = (known after apply)
      + manifest = jsonencode(
            {
              + apiVersion = "v1"
              + kind       = "Service"
              + metadata   = {
                  + labels    = {
                      + app.kubernetes.io/component = "server"
                      + app.kubernetes.io/name      = "argocd-server"
                      + app.kubernetes.io/part-of   = "argocd"
                    }
                  + name      = "argocd-server"
                  + namespace = "argocd"
                }
              + spec       = {
                  + ports    = [
                      + {
                          + name       = "http"
                          + port       = 80
                          + protocol   = "TCP"
                          + targetPort = 8080
                        },
                      + {
                          + name       = "https"
                          + port       = 443
                          + protocol   = "TCP"
                          + targetPort = 8080
                        },
                    ]
                  + selector = {
                      + app.kubernetes.io/name = "argocd-server"
                    }
                }
            }
        )
    }

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

Am I mistaken about the import line or is this just a bug?
