### Motivation i try to enable the topic level geo-replication in my cluster, when i execute `./pulsar-admin topics set-replication-clusters public/default/repl-test --clusters standalone,aliyun-test`, i got error: ```java 2022-07-19T09:05:09,444+0000 [AsyncHttpClient-7-1] WARN org.apache.pulsar.client.admin.internal.BaseResource - [http://localhost:8080/admin/v2/persistent/public/default/repl-test/replication] Failed to perform http post request: javax.ws.rs.NotAllowedException: HTTP 405 Topic level policies is disabled, to enable the topic level policy and retry. Topic level policies is disabled, to enable the topic level policy and retry. Reason: Topic level policies is disabled, to enable the topic level policy and retry. ``` after enable the topic error, try again, i got a `500` error: ``` 2022-07-21T03:37:17,796+0000 [AsyncHttpClient-7-1] WARN org.apache.pulsar.client.admin.internal.BaseResource - [http://localhost:8080/admin/v2/persistent/public/default/repl-test/replication] Failed to perform http post request: javax.ws.rs.InternalServerErrorException: HTTP 500 Topic policies service is disabled. --- An unexpected error occurred in the server --- Message: Topic policies service is disabled.
