Custom Field code

@metinazoz I don’t know what is wrong, although I only tested the code on the backend using this code:

import { authentication } from 'wix-members-backend'

export const createMember = async (email, password) => {
    let options = {
        contactInfo: {
            firstName: "Test",
            lastName: "Test",
            coins: 100,
        },
    }

    try {
        const registrationResult = await authentication.register(
            email,
            password,
            options
        )
        console.log(registrationResult)
    } catch (error) {
        console.error(error)
    }
}
