how do I make requests with node js grpc server vue js - node.js

Question

I am having such a problem when sending a request to the grpc server with vuejs, how can I do?
How can I create a nodejs grpc server and use vue js as a client to send a request and get a response.
MyServer Code here;
const grpc = require("grpc");
const loader = require("#grpc/proto-loader")
const packageDef = loader.loadSync("user.proto", {});
const object = grpc.loadPackageDefinition(packageDef);
const userPackage = object.userPackage;
const server = new grpc.Server()
server.addService(userPackage.User.service, {
"createUser": createUser,
})
const users = []
server.bind('0.0.0.0:5000', grpc.ServerCredentials.createInsecure())
console.log('Server running at http://127.0.0.1:5000')
function createUser(call, callback) {
const userItem = {
id: users.length + 1,
name: call.request.name,
lastname: call.request.lastname
}
users.push(userItem)
console.log('_', call)
console.log('cb', callback)
callback(null, userItem);
}
server.start()
My user.proto here;
syntax = "proto3";
package userPackage;
service User{
rpc createUser(UserItem) returns (UserItem); //unary
}
message UserItem{
int32 id = 1;
string name= 2;
string lastname= 3;
}
and My Client Code here;
<script>
import {UserClient} from './proto/proto-gen/user_grpc_web_pb'
import { UserItem} from './proto/proto-gen/user_pb'
created(){
this.client=new UserClient('http://0.0.0.0:5000',{})
const item=new UserItem()
item.setId(1)
item.setName('aaa')
item.setLastname('bbb')
this.client.createUser(item,{'Access-Control-Allow-Origin': '*'},(err,response)=>{
console.log(`error`, err)
console.log(`response`, response)
})
},
</script>
Error is here;
error {code: 2, message: "Http response at 400 or 500 level", metadata: {…}}
