We are using MirrorMaker to replicate topics across clusters in AWS. As the process is starting up, we are getting a NullPointerException when MirrorSourceConnector is calling `isCycle`. Retrieving the `upstreamTopic` on [this line of code|https://github.com/apache/kafka/blob/cc582897bfb237572131369a598f7869220b43dc/connect/mirror/src/main/java/org/apache/kafka/connect/mirror/MirrorSourceConnector.java#L497] is returning null, which causes the NPE on the next line. -- This message was sent by Atlassian Jira (v8.20.10#820010)
