Issue with NextAuth, PrismaAdapter, and Resend with magic link: Not Saving name and tenantId in User Table and Passing Extra Props

[jovemdan]

Hi 👋
Problem Description
I'm facing an issue when trying to save the name and tenantId fields in the User table using NextAuth with PrismaAdapter and the resend provider with magic link. The goal is to save these fields when a user registers or logs in using the resend provider, but currently only the email field is being saved correctly.

Steps to Reproduce
Create a new user using the resend provider.
Check the saved fields in the User table.
Expected Behavior
The name and tenantId fields should be saved along with the email in the User table.

Current Behavior
Only the email field is being saved correctly in the User table. The name and tenantId fields are blank.

Relevant Code
HandleSaveClick Component:

const handleSaveClick = async () => {
  const formData = getValues()

  const createdTenant = await createTenant(
    formData.tenant,
    formData.emailTenant,
    true,
    formData.cnpj,
    formData.phoneTenant,
    formData.freePlanEndDate,
  )

  signIn('resend', {
    email: 'test@gmail.com',
    name: 'Test',
    tenantId: createdTenant.id,
    callbackUrl: '/admin',
  })
}

NextAuth Configuration:

providers: [
  GoogleProvider({
    // ...
  }),
  {
    id: 'resend',
    type: 'email',
    sendVerificationRequest,
    profile(profile: any) {
      return {
        id: profile.sub,
        name: profile.name,
        email: profile.email,
        tenantId: profile.tenantId,
      }
    },
  },
],
callbacks: {
  async jwt({ token, user, trigger, session }: any) {
    // ...
  },
  async session({ session, token }: any) {
    // ...
  },
},
adapter: PrismaAdapter(prisma),
session: {
  strategy: 'jwt',
},

SendVerificationRequest Function:

import { resend } from '../lib/resend'

export async function sendVerificationRequest(params: any) {
  const { url, name, tenantId } = params
  const { host } = new URL(url)

  try {
    const data = await resend.emails.send({
      from: 'Acme <onboarding@resend.dev>',
      to: 'test@gmail.com',
      subject: `Log in to ${host}`,
      text: text({ url, host, name, tenantId }),
    })

    return { success: true, data }
  } catch (error) {
    throw new Error('Failed to send the verification Email.')
  }
}

function text({ url, host }: any) {
  return `Sign in to ${host}\n${url}\n\n`
}

User Schema:

model User {
  id            String    @id @default(cuid())
  name          String?
  email         String?   @unique
  emailVerified DateTime?
  image         String?
  Tenant        Tenant?   @relation(fields: [tenantId], references: [id], onDelete: Cascade)
  tenantId      String?
  Account       Account[]
  Session       Session[]
}

Next js version: 13.4.1
Prisma version: 5.1.1
NextAuth version: 4.22.1
Resend version: 1.0.0

Other Information
I've tried following the steps from the official NextAuth documentation, but the name and tenantId fields are not being saved.
The configurations and code are detailed above. Any additional guidance on what might be causing this issue would be greatly appreciated.
