Could you please clarify why the code snippet below is returning audiences instead of an empty array?
return Audience.find()
.exec((err, audiences) => {
if (err) return errorHandler.handle('audienceService', err);
return Promise.resolve([]);
});
After completing the exec function, you are now back in the callback. To utilize the promise returned by exec, remember to apply then on it, which is detailed here. Additionally, there is no necessity for Promise.resolve:
return Audience.find()
.exec()
.then(audiences => [])
.catch(err => errorHandler.handle('audienceService', err));
