To see the error do the following:
yarn && yarn start
- Go to localhost:8080
- Open the console (so you can see the errors
- Drag one of the list items on top of another list item.
You should see an error stating:
Uncaught Error: Cannot call endDrag while not dragging.
For contrast, in a different terminal window, run yarn webpack:dev
. This is a slightly different config,
but the key seems to be the lack of minification.
Go back to the browser, and drag again. You should see console messages for hovering and dropping.
