Error: [vuex] do not mutate vuex store state outside mutation handlers.

[MathieuDerelle]

it happens in a tree with at least 3 levels

when moving node "test" into "test 2" (as a child)

the stacktrace points to this line

vuetify-draggable-treeview/src/DraggableTreeviewNode.vue

Line 140 in 2176225

this.$set(this.localValue.children, index, value);

which tells me that that array children is not cloned

I am also experiencing this issue when the tree gets to level 3 or more.
