ondragstart and ondragend error

[brunokunace]

When set ondragstart and ondragerror props, receive error

[ERROR|/usr/local] {"text":"http://localhost:8080/_nuxt/2.js:5036_Uncaught TypeError: Cannot read property 'slice' of undefined_52_TypeError: Cannot read property 'slice' of undefined","level":"ERROR"}

eachDraggable and eachDroppable work fine, but i need to test when drag end, because i dont put "folder" inside another, only "files"
