How frequently does the bug occur?

Always

Description

const realm = Realm.open({ schema: [ PlaceSchema, LocationSchema, ContactInformationSchema, EditorialSummarySchema, ReviewSchema, PhotoSchema, AuthorAttributionSchema, TextSchema, displayNameSchema, ], deleteRealmIfMigrationNeeded: true, }); try { const places = realm.objects('Place'); // Retrieve all 'Place' objects const placesArray = Array.from(places); console.log('Data fetched from Realm:', placesArray); return placesArray; } catch (error) { console.error('Error fetching data from Realm:', error); } finally { realm.close(); }

expected realm should close but it throw error

Error: Transaction_ended and app crash

and some times=> Error: List is no longer valid. Either the parent object was deleted or the containing Realm has been invalidated or closed.

My guess is that your data model has links, and Array.from() does not copy deeply. It might be better to use the spread operator if you really need to copy the objects.

i have tried but having same issue

realm = await openRealm(); const response = realm.objects('Place'); const businesses = [...response]; // Array.from(response); if (Array.isArray(businesses) && businesses.length > 0) { const formattedAddressWords = businesses[0]?.formattedAddress?.length > 0 && businesses[0]?.formattedAddress?.split(' '); const lastWord = formattedAddressWords[formattedAddressWords.length - 1]; dispatch(setLocation(lastWord)); fetchAllPlacesDetails(businesses); dispatch(setPlacesDataLength(businesses.length)); realm.close()

[kneth]

The issue is that neither Array.from() or ... will create true POJOs, and once you close the Realm (realm.close()), any managed (Realm) objects will be invalidated.

The following code snippet illustrates it:

const Realm = require("realm");

const A = {
  name: "A",
  properties: {
    a: "int",
  },
};

const B = {
  name: "B",
  properties: {
    a: "A",
    b: "int",
  },
};

let realm = new Realm({ schema: [A, B] });
realm.write(() => {
  realm.create("B", { b: 11, a: { a: 22 } });
});

let bs = realm.objects("B");
let pojos1 = [...bs];
console.log(`Before close: ${pojos1[0] instanceof Realm.Object} ${pojos1[0].a instanceof Realm.Object}`);

let pojos2 = bs.toJSON();
realm.close();
console.log(`After close: ${pojos2[0] instanceof Realm.Object} ${pojos2[0].a instanceof Realm.Object}`);

If you need to copy deeply from Realm, toJSON() is your best option.
