Code Sample

I used an example from your documentation

import Realm from 'realm';

const CarSchema = {
  name: 'Car',
  properties: {
    make: 'string',
    model: 'string',
    miles: { type: 'int', default: 0 },
  },
};

const realm = new Realm({ schema: [CarSchema] });

export const queryCars = () => {
  return realm.objects('Car');
};

export const addCar = () => {
  realm.write(() => {
    const myCar = realm.create('Car', {
      make: 'Honda',
      model: 'Civic',
      miles: 1000,
    });
    myCar.miles += 20; // Update a property value
  });
};

export default realm;

Version of Realm and Tooling

Realm JS SDK Version: 2.20.0
Node or React Native: React Native - 0.57.5
Client OS & Version: MacOS - Mojave
Which debugger for React Native: React Native Debugger (Chrome based)

Temporary Solution:

Commeting out this line worked but this is not the best solution: Path: node_modules/realm/lib/index.js comment out this line: realmConstructor.Sync._initializeSyncManager(createUserAgentDescription());
