              #     the field to update. For example, to change the number of workers
              #     in a cluster to 5, the `update_mask` parameter would be
              #     specified as `config.worker_config.num_instances`,
              #     and the `PATCH` request body would specify the new value, as follows:

              #         }
              #     Similarly, to change the number of preemptible workers in a cluster to 5,
              #     the `update_mask` parameter would be
              #     `config.secondary_worker_config.num_instances`, and the `PATCH` request
              #     body would be set as follows:

              #     `status.state` can be one of the following: `ACTIVE`, `INACTIVE`,
              #     `CREATING`, `RUNNING`, `ERROR`, `DELETING`, or `UPDATING`. `ACTIVE`
