Steps to Reproduce

Sorry, but when i tried with our devices and reproduce code. It worked fine in all times. I think it happen in some special case.

Code Sample

    const currentSchema = new studifySchema().current();
    const syncConfig = {
      sync: {
        user,
        url: realmUrl(),
        error: err => console.log('realm error', err),
      },
      path: realmDbLocation(userID),
      ...currentSchema,
    };

   studifyDB = await Realm.open(syncConfig).progress((transferred, transferable) => {
        // ... handler
    });
