I have upgraded my mongo QA environment from v3.6 to v4.0.23. I am running sharded cluster with 14 mongos, 3 config servers and 3 shard servers. I have upgraded all three components successfully to v4.0.23.
Now I am trying execute last step of upgrade v3.6 to v4.0.23 which is enabling backwards-incompatible 4.0 features. But I am getting below error, even if I retried command, restarted mongos, config and shard servers.
// mongos> db.adminCommand( { setFeatureCompatibilityVersion: "4.0" } ) { "ok" : 0, "errmsg" : "Regular expression is invalid UTF-8", "code" : 5108300, "codeName" : "Location5108300", "operationTime" : Timestamp(1621314272, 3), "$clusterTime" : { "clusterTime" : Timestamp(1621314272, 3), "signature" : { "hash" : BinData(0,"F/Ukgpx8acf5fBuOtKfw0gyz3L4="), "keyId" : NumberLong("6934901981374840833") } } }
