Description
What is going wrong?
Hi Team,
I am executing getPlanCache().clear() after connecting to secondary node directly but it's failing with mongosh version 2.1.1 }}but it's successful with {{1.10.6
MongoDB Version used : 6.0.12
Please find the same command executed with mongosh version 2.1.1 and 1.10.6 where 2.1.1 is failing while executing getPlanCache().clear()
Mongosh version: 2.1.1

Steps to Reproduce
Use a MongoDB replica set with 6.0.12
Connect to the secondary node directly with mongosh version: 2.1.1 without passing any information related to replica set.
Execute db.getMongo().setReadPref('secondary') so we can execute queries against secondary node.
use any database and collection in mongosh where you have some data and execute db.<collectionname>.getPlanCache().clear() . This will generate an error that we can't perform operation against secondary node.
Expected Results
Command should be successful as we have allowed queries against secondary node using db.getMongo().setReadPref('secondary'). We are seeing the expected results in mongosh 1.10.6
Actual Results
We are getting error:
MongoServerError: not primary and secondaryOk=false - consider using db.getMongo().setReadPref() or readPreference in the connection string
