javascript - Angular UI 模式未显示

Question

我正在尝试添加一个模式，当用户单击这样创建的元素时会弹出：

<li ng-repeat="task in tasks | filter:{Status: 0}" class="list-group-item list-group-item-danger" ng-click="getTask(task)">

这是 getTask 函数：

    $scope.getTask = function (task) {
        taskService.getTask(task.Id)
            .then(task => {
                var modalInstance = $uibModal.open({
                    animation: true,
                    templateUrl: "Content/partials/TaskModal.html",
                    controller: "taskModalController",
                    resolve: {
                        task: function () {
                            return task
                        }
                    }
                });

                modalInstance.result.then(task => {
                    if (task)
                        updateTask(task); 
                });
            })
    };

模板只是一个带有表单的 div。

<div class="panel panel-primary">
    <div class="panel-heading">Edit Task</div>
    <div class="panel-body">
        <form name="EditTask" ng-submit="saveTask()" class="form-inline mb-5">
            <div class="form-group col-lg-4">
                <label for="Assignee">Assignee</label>
                <input type="text" name="Assignee" class="form-control" required ng-model="EditTask.Assignee" ng-minlength="5" />
            </div>
            <div class="form-group col-lg-4">
                <label for="Assignment">Assignment</label>
                <input type="text" name="Assignment" class="form-control" ng-model="EditTask.Assignment" required ng-minlength="5" />
            </div>
            <div class="form-group col-lg-4">
                <input type="submit" name="Save" value="Save" class="btn btn-success btn-lg"
                       ng-disabled="EditTask.$invalid" />
            </div>
        </form>
    </div>
</div>

单击元素时，实际上会创建模态，但是它是完全不可见的。可以单击按钮，将鼠标悬停在按钮上时指针会发生变化，检查文件表明信息已正确传递。

我在这里错过了什么阻止我展示这个模式？
