Attempting to getUri() returns error "instanceInfo" is undefined

[cbryant24]

Versions

• NodeJS: v15.10.0
• mongodb-memory-server-*: 7.0.0-beta.26
• mongodb: 4.0.20
• mongoose: 5.11.19
• system: MacOS Big Sur Apple M1

package: mongo-memory-server

What is the Problem?

I Run npm run test and the test throws an error when invoking await mongoServer.getUri() stating the "instanceInfo" is undefined

Code Example

This repo can also be cloned and run to reproduce the problem if using an apple macbook with an m1 chip
https://github.com/cbryant24/mongo-memory-server

import mongoose from "mongoose";
import { MongoMemoryServer } from "mongodb-memory-server";

// May require additional time for downloading MongoDB binaries
jasmine.DEFAULT_TIMEOUT_INTERVAL = 600000;

let mongoServer: any;

beforeAll(async () => {
  mongoServer = new MongoMemoryServer();
  const mongoUri = await mongoServer.getUri();
  await mongoose.connect(mongoUri, (err) => {
    if (err) console.error(err);
  });
});

afterAll(async () => {
  await mongoose.disconnect();
  await mongoServer.stop();
});

Do you know why it happenes?

no

sorry, if you didnt read the changelog, you wouldnt know - there is no migration guide yet

getUri (on all classes) is now sync, not an promise anymore, an instance needs to be manually started with .start or directly with .create

I'm able to connect now aftering running this code for a jest setup

beforeAll(async () => {
  mongoServer = new MongoMemoryServer();
  await mongoServer.start();

  const mongoUri = mongoServer.getUri();

  await mongoose.connect(mongoUri, (err) => {
    if (err) console.error(err);

    return;
  });
});

but it seems to hang and not run my tests. Anything I am missing?

[cbryant24]

Actually I was able to fix it by adding useNewUrlParser options to the connect method

  await mongoose.connect(mongoUri, { useNewUrlParser: true }, (err) => {
    if (err) console.error(err);
  });
