vuex2 mapActions 報錯 `unknown action type: xxxx`

export const setBreadCrumb = ({ dispatch }, data) => {
    dispatch('SET_BREADCRUMB', data)
}

 

當調用的時候報[vuex2] mapActions 報錯 `unknown action type: setBreadCrumb`

后台改成 

export const setBreadCrumb = ({ commit }, data) => {
    commit('SET_BREADCRUMB', data)
}

未報錯
