The server is not the primary and did not execute the operation

[cluster-ClusterId{value='6322852d9dxxxxxxx', description='null'}-10xxxxxx:27xxxx] INFO cluster - Monitor thread successfully connected to server with description ServerDescription{address=10.xxxx:27xxx, type=STANDALONE, state=CONNECTED, ok=true, version=ServerVersion{versionList=[3, 4, 24]}, minWireVersion=0, maxWireVersion=5, maxDocumentSize=16777216, roundTripTimeNanos=497021}

也不是REPLICA_SET，为什么报错不是primary

Start with the reported cluster connection log, especially the STANDALONE server description and the “not primary” error. No source file, test, entry point, or completion criteria are identified in the issue, so the relevant DataX MongoDB connection path and the operation producing the error must first be located.
