Hello, @Ilayda_B.

You cannot use a function return and then at the same time.
You already had a similar error in your previous topics:

Struggling with making a dataQueryBuilder in Flutter

Hello, @Ilayda_B. You need to call code like this: var query = DataQueryBuilder() ..related = ['linkedVenue']; var dbdata = await Backendless.data.withClass<Exhibit>().find(query); // working with result IMPORTANT: You should to use callback(then) or await keyword but not both at the same time(your example uses then and await at the same time for one method). Best Regards, Nikita.
