      Description

      This test sometimes fails with:

       ERROR: No replica set members match selector "Primary()" (ServerSelectionTimeoutError)

       ServerSelectionTimeoutError: No replica set members match selector "Primary()"
      

      I think this might just be a race condition due to the short serverSelectionTimeoutMS. Increasing the timeout to 250ms might reduce the frequency.
