Accounts.findUserByUsername(username) is undefined after the user account creation

I am having a problem with Account-password package. I am creating a new user on client side as follows

createNewUser(event) {
    event.preventDefault();
    console.log("create new user");
    username = ReactDOM.findDOMNode(this.refs.createUsernameInput).value.trim();
    password = ReactDOM.findDOMNode(this.refs.createPasswordInput).value.trim();
    repasswd = ReactDOM.findDOMNode(this.refs.createPasswordAgain).value.trim();
    if (password != repasswd) {
      alert("password values didn't match." + " <br/>" +
        "Please retry.");
    } else {
      //TODO: do this on server instead
      id = Accounts.createUser({
        username: username,
        password: password
      });
      console.log("looking for: " + username);
      user = Meteor.call('doesUserExist', username);
      console.log("user: " + user);
      //Roles.addUsersToRoles(id, "trial");

    }
  };

Corresponding server side method is as follows

import {Meteor} from 'meteor/meteor';

Meteor.methods({
  doesUserExist : function (username) {
    console.log("inside server method: doesUserExist");
    if (Accounts.findUserByUsername(username) != null) {
      return true;
    } else {
      return false;
    };
  },
});

Once the user is created, based on the server console logs, the “doesUserExist” method is called correctly on the server side. I am expecting the value of user to be either true or false on the client side. However, I am getting undefined.
what am I missing here?

Thanks

Your Meteor.call() needs a callback:

console.log("looking for: " + username);
user = Meteor.call('doesUserExist', username, (error, result) => {
  if (error) {
    // do something with the error
  } else {
    console.log("user: " + result);
  }
});

Or you can use async/await:

that is because use is created after method call, so checking for it inside call will return undefined. what you can do is add Meteor.users.after.insert(function(userId, doc) function to return value

I changed the meteor.method to following and it seems to work

async createUserAccount(username, password) {
    console.log("inside server method: createUserAccount");
    const result = await Accounts.createUser({
      username: username,
      password: password
    });

    const newUserId = await Accounts.findUserByUsername(username);
    Roles.addUsersToRoles(newUserId, "trial");
    
    return result;
  },

I can see that the role “trial” is added to the new user that I just created.

Thanks guys Appreciate your help.
