I’m also running into this issue only in jest test (in-memory or not)

the same code directly in node work fine

to get it working in jest:

new Date().toISOString();

Facing this issue myself with jest tests using inMemory Realm.

Works fine on 3.6.5

I forgot to mention that I use in memory realm for Jest tests, maybe there is an issue?

@kneth The schema I pass to Realm constructor is

  const realmConfig = user.createConfiguration({
    schema,
    schemaVersion,
    sync: {
      url: `~/app`,
      fullSynchronization: true
    }
  });
  const realm = new Realm(realmConfig);

where schema is:

export const schema = [
  ConfigRealmModel.schema,
  CollectionModel.schema,
  CollectionItemModel.schema,
  ImporterAuthenticationModel.schema,
  TransferModel.schema,
  TransferCollectionModel.schema,
  TransferCollectionItemModel.schema,
  LicenseRequestModel.schema
];
export const schemaVersion = 1;

So as I understand, it is done in the same manner by passing JS object directly. Also, it worked with 4.0.0 alpha.
