how can I pass data like the name of my user and put it in the post they created - node.js

Question

so I am making an application for events and for some reason when a user creates an event the even info shows but the user info like their name and photo doesn't show up please help I've been having this problem for almost a week now.
THIS IS THE componentDidMount function
async componentDidMount() {
const { data } = await getCategories();
const categories = [{ _id: "", name: "All Categories" }, ...data];
const { data: events } = await getEvents();
this.setState({ events, categories });
console.log(events);
}
THIS IS THE STATE
class Events extends Component {
state = {
events: [],
user: getUser(),
users: getUsers(),
showDetails: false,
shownEventID: 0,
showUserProfile: false,
shownUserID: 0,
searchQuery: ""
};
THIS IS THE EVENTS FILE WHERE THE USER'S NAME AND PHOTO SHOULD BE DISPLAYED
<Link>
<img
className="profilePic mr-2"
src={"/images/" + event.hostPicture}
alt=""
onClick={() => this.handleShowUserProfile(event.userId)}
/>
</Link>
<Link style={{ textDecoration: "none", color: "black" }}>
<h4
onClick={() => this.handleShowUserProfile(event.userId)}
className="host-name"
>
{getUser(event.userId).name}
</h4>
</Link>
This is the userService file where the getUser function is
import http from "./httpService";
const apiEndPoint = "http://localhost:3100/api/users";
export function register(user) {
return http.post(apiEndPoint, {
email: user.email,
password: user.password,
name: user.name
});
}
export function getUsers() {
return http.get(apiEndPoint);
}
export async function getUser(userId) {
const result = await http.get(apiEndPoint + "/" + userId);
return result.data;
}
This is the eventService file where the event is
import http from "./httpService";
const apiEndPoint = "http://localhost:3100/api/events";
export function getEvents() {
return http.get(apiEndPoint);
}
export function getEvent(eventId) {
return http.get(apiEndPoint + "/" + eventId);
}
export function saveEvent(event) {
if(event._id){
const body = {...event}
delete body._id
return http.put(apiEndPoint + '/' + event._id, body)
}
return http.post(apiEndPoint, event);
}
export function deleteEvent(eventId) {
return http.delete(apiEndPoint + "/" + eventId);
}

First, you have some mistakes to use the class in <div> elements.
please use className instead class.
And then second I am not sure what it is.
class Events extends Component {
state = {
... ...
user: getUser(),
... ...
};
As you seen getUser() function requires one parameter userId.
But you did not send this.
So you met internal server error to do it.
Since I did not investigate all projects, I could not provide perfectly solution.
However, it is main reason, I think.
Please check it.
