      When connecting to a cluster using a SRV record, the Node driver hangs indefinitely if the read preference is primary and the first SDAM event returns a topology type of ReplicaSetNoPrimary, even though the cluster has a primary and is in a healthy state.

      Steps to reproduce:

      const { MongoClient } = require('mongodb');
const client = new MongoClient(
 "mongodb+srv://<redacted>/admin?readPreference=primary&appname=MongoDB%20Compass%20Dev&authSource=admin&ssl=true",
 { readPreference: "primary", connectWithNoPrimary: true, checkServerIdentity: true, sslValidate: true }
);
client.connect((err, c) => {
  // This block will never get executed.
  console.log('in connected block');
  console.log(err);
  console.log(c);
});

      Switching to primaryPreferred as the read preference will always connect.
