I am creating a new collection in a new database on the sharded environment.

I am getting the following error while coll.insertMany(list).

Exception in thread "main" com.mongodb.MongoCommandException: 
Command failed with error 133: 'unable to target write op for collection dbname.collection:: caused by :: 
FailedToSatisfyReadPreference: Could not confirm non-existence of database "dbname" due to inability to query the config server primary :: caused by :: 
FailedToSatisfyReadPreference: could not find host matching read preference { mode: "primary" } for set csReplSet' on server ip:27017. 
The full response is { "ok" : 0, "code" : 133, "errmsg" : "unable to target write op for collection dbname.collection:: caused by ::

There is possibility of read preference member is not available in replicaset in your case i.e primary not available.

For one or more reason's.

  • Failover scenario when newely primary is getting elected.
  • Majority of server's not available leaving no primary available.

It looks like Read Preference is creating problem in your end.

Please go thru read preference and set which is more appropriate for your application

https://docs.mongodb.com/manual/reference/read-preference/

If your issue is something related to the one which is mentioned in below jira then we need mongo version 3.3.11 and currently we have only 3.2.9 released.
