Source Data from vuex

Hi, I'm trying to use vuex to put data into your component, but unfortunately I get following errors:

Error in callback for watcher "function () { return this._data.$$state }": "Error: [vuex] do not mutate vuex store state outside mutation handlers."(found in )

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

<DraggableTree :data="dashboardMenu" draggable="draggable" :cross-tree="true" @drag="ondrag" ref="tree1" @change="treeChange">

                        return 'skip children'

                    if (!childNode._vm) {
                        console.log(childNode);

                    this.$set(childNode, 'droppable', childNode._vm.level <= childNodeMaxLevel)
                })
            },
}

Could you help me please?
