问获取脚本:无法设置未定义的属性‘TypeError’

EN

我有以下AngularJS代码：

HTML：

<input type="text" class="form-control" id="repoInput" style="margin: 10px 0 10px 0" placeholder="Stored Procedures" ng-model="procedureInput" uib-typeahead="key for key in getScripts(selected.branchClone, selected.type) | filter:$viewValue | limitTo:10" typeahead-on-select='addStoredProcedure($item, selected);procedureInput = "";' typeahead-loading="templateLoading" typeahead-wait-ms="100" />

$scope.getScripts = function (repo, template) {
items.then(function (payload) {
            $scope.repos[template] = template;
            $scope.repos[template][repo] = repo;
            console.log($scope.repos[template]);
            console.log(repo);
            console.log($scope.repos[template][repo]);
            $scope.repos[template][repo]["scripts"] = payload.data.value;
            deferred.resolve(payload.data.value
                .map(function (x) {
                    return x["path"];
                }));
        });
}

我确实有template变量和repo变量的值。但是，尽管如此，我还是收到一个错误

$scope.repos[template][repo]["scripts"] = payload.data.value;说
