Why is the function being executed twice?

Question

JavaScript

EventService.getDataFromDB().then(function(result) {
        if (result.length > 0) {
            $scope.items = EventService.populateData(result).items
            $scope.categories = EventService.populateData(result).categories
            console.log('Готово (база)!');
        } else {
            EventService.getDataFromApi().then(function() {
                EventService.getDataFromDB().then(function(result) {
                    $scope.items = EventService.populateData(result).items
                    $scope.categories = EventService.populateData(result).categories
                    console.log('Готово (API)!');
                })
            })
        }
    });

For some reason, this piece of code is executed twice - the news is duplicated, the message falls out twice in the console. There are no more calls anywhere, what's the matter? Broke my head.
