why i can not update data using vuex module?

Question

here is my component

     methods:{
         ...mapActions(['udpateUsers']),
         Update(userID){
             let formData = new FormData();
             formData.append('new_name',this.editUser.new_name);
             formData.append('_method', 'PUT');      
             let config = {
                 headers:{
                     'Content-Type':'multipart/form-data',         
                 }        
             }
             this.udpateUsers(userID,formData,config);
         }

when i click update button the formData can not be sent to the server but when i console it the FormData is has all the fields

here is my modules

        mutations:{
             ADD_USER: (state,response)=>{
                 state.Users = response;
             },
             UPDATE_USERS: (state,response)=>{
                 state.Users = response;
             }
         },
         actions:{
             udpateUsers: ({commit},userID,formData,config)=>{  
                     http.put("/admin/update/"+userID,formData,config)
                     .then((response)=>{
                         commit("UPDATE_USERS",formData);  
                         console.log(response);
                     })
                     .catch((error)=>{
                         console.log(error.response);
                    })
             }
         }
     export default auth

i think the error will be my commit mutation

You can't pass multiple parameters as payload to Vuex Actions. You'll need to wrap it all up in an object and pass it as a single param.

udpateUsers: ({commit}, { userID, formData, config }) => {
    // send to backend
}

this.udpateUsers({ userID, formData, config });

EDIT: From comments, it seems that you're using PUT method instead of POST in your VueX implementation, which is why your backend wasnt getting the data.
