Unable to assign role upon member registration

I’m unable to get the following code to assign a role to members upon registration. Would really appreciate if anyone could please point out what’s wrong. Thanks!

// Custom signup

import { authentication } from 'wix-members';
import { assign } from 'backend/role';

$w.onReady(function () {

    // Click "Run", or Preview your site, to execute your code
    $w('#button2').onClick ((event) => {
        const email = $w('#input2').value;
        const password = $w('#input1').value;
        const options = {
            contactInfo: {
                firstName: $w('#input4').value,
                lastName: $w('#input3').value
            }
        };
        var role = "";
        if ($w('#dropdown1').value=="Employer") {
            role = "c02c480a-20ae-4cd7-85ff-d0d00d60ecda";
        } else if ($w('#dropdown1').value=="Employee") {
            role = "32c341be-8b80-4dec-ab82-8d39f729680c";
        }
        console.log(role);
        authentication.register(email, password, options).then((results) => {
            console.log("Hit correct branch");
            assign(results.member._id, role);
            console.log("Successfully assgined role");
        })
        .catch((error) => {
            console.log("Hit error branch");
            console.error(error);
        };
    });

});
// backend/role.jsw

import { authorization } from 'wix-members-backend';

export function assign(member, role) {
    const roleId = role;
  const memberId = member;

  return authorization.assignRole(roleId, memberId, {suppressAuth: true})
    .then(() => {
      console.log("Role assigned to member");
    })
    .catch((error) => {
      console.error(error);
    });
}

When I try to sign up and open the web console, only the role ID would be printed (console.log(role)) but “Hit correct branch” would not be printed.

Do you get results at this point …?

authentication
.register(email, password, options)
.then((results)=>{
    console.log("RESULTS: "; results);
});

Is the role/role-ID already included inside the resulting-object, at this point?

Directly after the registration you gets logged-in. This causes a page-reset.

But wait!!! What??? → You get automatically logged-in !!!

Ok, maybe you need to use in this case an → “onLogin()” event-trigger???

Something like…

MASTER-PAGE:

$w.onReady(()=>{
	wixMembers.authentication.onLogin((member)=> {
		console.log("Member: ", member);
	});
});
