Enabling useUnifiedTopology results in stack overflow when connecting to uninitialized replica set

    • Type: Icon: Bug Bug
    • Resolution: Fixed
    • Priority: Icon: Major - P3 Major - P3
    • 3.3.5
    • Affects Version/s: 3.3.4
    • Component/s: None
    • None

      Steps to reproduce:
      1. Start a single-node replica set but do not initialize it.
      mongod --replSet repro --port 37017 --dbpath ./data/db --logpath ./data/mongodb.log --fork
      2. Run the following Node.js code (using Node.js Driver 3.3.4):

      const MongoClient = require('mongodb').MongoClient;

const url = 'mongodb://localhost:37017';

const client = new MongoClient(url, {useUnifiedTopology:true});

client.connect((err, client) => {
  client.db('admin')
        .command({replSetInitiate: { _id: 'repro', members: [{_id: 0, host: 'localhost:37017'}] }},
                 (err) => console.log(err));
});

      This results in a stack overflow:

      $ node test.js
/Users/james/Documents/mongodb-cases/00618581/repro/node_modules/mongodb/lib/core/sdam/topology.js:435
      process.hrtime(),
      ^

RangeError: Maximum call stack size exceeded

      If you remove useUnifiedTopology:true, the code works as expected and initializes the replica set.
