I have used the DndProvider wrapper in my main file It was working properly before. But after I imported and used useDrop it started throwing the drag drop context error
/* eslint-disable no-unused-vars */

const AAWhatsapp = () => {
const [draggedComponents, setDraggedComponents] = useState([])
const [canvasSize, setCanvasSize] = useState({ width: 800, height: 600 })
const handleSidebarItemClick = (componentType) => {
setDraggedComponents((prev) => [...prev, { type: componentType, position: { x: 0, y: 0 } }])
}
const handleDrag = (index, delta) => {

I tried creating a separate DndProviderWrapper component and used it to wrap my entire application. Didn't work
const [, drop] = useDrop({
accept: 'SIDEBAR_ITEM',
drop: (item) => handleDropFromSidebar(item)
handleDropFromSidebar
where is this defined?
