      Description

      When attempting to restart a connector, the following is logged by Connect:

       

      ERROR Uncaught exception in REST call to /connectors/my-connector/tasks/0/restart (org.apache.kafka.connect.runtime.rest.errors.ConnectExceptionMapper)
      java.lang.IllegalArgumentException: "uriTemplate" parameter is null.

          at org.apache.kafka.connect.runtime.rest.resources.ConnectorsResource.restartTask(ConnectorsResource.java:218)
      

      Resubmitting the restart REST request will usually resolve the problem.
