'objectType' must be of type : string

Hi im getting this error as soon as i call one on my methods inside realm.ts which is below

My models with realm schemas (models.ts)

import { ICity, IUser } from './interfaces'
import Realm , { ObjectSchema, PropertyType } from 'realm'

export class City implements ICity {

  // static get () { return realm.objects(City.schema.name) }
  static schema : ObjectSchema = {
    name: 'City',
    primaryKey : 'id',
    properties : {
      id : {type : 'string'},
      cityName : {type : 'string'},
      localImg : {type : 'string', optional: true},
      sourceLogo : {type : 'string', optional: true},
      cityCode : {type : 'list'},
    }
  }

  constructor(cityName?: string, cityCode?: string, sourceLogo?: string, localImg?: string) {
    this.cityName = cityName    
    this.cityCode = cityCode
    this.sourceLogo = sourceLogo
    this.localImg = localImg
  }

  public cityName: string;
  public localImg: string;
  public sourceLogo: string;
  public cityCode: string;
}

export class User implements IUser {

  //TODO: hash users pw
  static schema : ObjectSchema = {
    name: 'User',
    primaryKey : 'id',
    properties : {
      id : {type : 'string'},
      fullName : {type : 'string'},
      user : {type : 'string'},
      pw : {type : 'string'},
      cities : {type : 'list', objectType: 'City'},
    }
  }

  public fullName: string;
  public user: string;
  public pw: string;
  public cities: Array<ICity>;

  constructor(fullName?: string, user?: string, pw?: string, cities?: Array<ICity>) {
    this.fullName = fullName
    this.user = user
    this.pw = pw
    this.cities = cities
  }
  
}

Where realm happens (realm.ts)

import Realm from 'realm'
import { ListView } from 'realm/react-native'
import uuid from 'uuid'
import { User, City } from '../types/models';

//export const userItemDS = new ListView.DataSource({rowHasChanged: (r1, r2) => r1.id !== r2.id})

export const getUsers = () => {
  const users = realm.objects('User').sorted('id', true)
  console.log(users);
  return users
}

export const getUser = (id : string) => {
  const user = realm.objectForPrimaryKey(User, id)
  console.log(user);  
  return user
}

export const saveUser = ({fullName, user, pw} : User) => {
  realm.write(() => {
    realm.create(User.schema.name, {
      id: uuid.v1(),
      fullName,
      user,
      pw
    })
  })
}


const realm = new Realm({schema: [User, City]})

ok its fixed, my problem was using the static property schema on my User object and passing the User constructor directly. Instead of doing :

const realm = new Realm({schema: [User, City]})

I have to do :

const realm = new Realm({schema: [User.schema, City.schema]})

Thanks everyone !

Hi @wilomgfx. Thanks for reaching out. My apologies for the delay in someone getting back to you. The Javascript team is rather small and one of our JS engineers is currently on vacation. We’ll try to get back to you as soon as we can!
