无法使用react-beautiful-dnd

Question

我有一个接收两组数据的组件，它是一个 react-beautiful-dnd DragDropContext如下

 render() {
    let index = -1;
    const dataSetOne = this.props.store!.getdata(1);
    const dataSetTwo = this.props.store!.getData(2);
    const allData = this.props.anotherStore!.getAllData();

    return (
        <DragDropContext onDragEnd={this.onDragEnd}>
          <Droppable droppableId="SIDE_MENU" direction="vertical" type="sections">
            {(provided, snapshot) => (
              <div
                {...provided.droppableProps}
                ref={provided.innerRef}
                onScroll={(e) => e.currentTarget.scrollTop}
              >
                {dataSetOne!.map((a, i) => {
                  index = i;
                  const currentData:any= allData.filter(/*logic*/)
                  return (
                    <MyDraggableComp
                      key={a.id!}
                      aes={a}
                      index={index}
                      data={currentData}
                    />
                  );
                })}
               {dataSetTwo.length > 0 ? (
                <MyDraggableComp
                  key="SOMEKEY"
                  aes={null}
                  index={index + 1}
                  data={dataSetTwo}
                />
                ) : null}
                {provided.placeholder}
              </div>
            )}
          </Droppable>
        </DragDropContext>
    );
  }

到目前为止，此代码运行良好，并且根据dnd实施准则正确实施了MyDraggableComp，其中包含{...sectionProvided.dragHandleProps}

现在已更改了后端，并且dataSetTwo永远不会为null或为空，因此希望删除条件并始终呈现它。

但移动了dataSetTwo.length>0条件，只是有了

            <MyDraggableComp
              key="SOMEKEY"
              aes={null}
              index={index + 1}
              data={dataSetTwo}
            />

导致此错误，我什至不了解与案件的关系以及要查找的内容？有人可以向我解释发生了什么以及如何解决？

Error: Invariant failed: 
      Cannot find drag handle element inside of Draggable.
      Please be sure to apply the {...provided.dragHandleProps} to your Draggable
