I'm trying to enable the dragula COPY function when I drag a "recipe" into a table.

When I try to do it, I get the error
Cannot read property '0' of undefined at applyDrop (service.js:80)

How can I fix this? i've spent so long on it.

I changed you dragula attributes to : ='"bag-one"' and it worked.

If you look at their example, the attribute is encapsulated in single and double quote:

<div dragula='"fifth-bag"'></div>

Hope this helps.
