404 Error while using node-appwrite createMagicURLToken

Hello all, I'm currently working on implementing a Next.js API that sends emails with a magic URL. However, I'm running into a 404 error saying 'The requested route was not found. Please refer to the API docs and try again.' I don't know where I did wrong and need your help, thank you.

// src/app/api/magic-url/email/route.ts
import { createAdminClient } from '@/lib/appwrite/server'
import { NextRequest } from 'next/server'
import { ID } from 'node-appwrite'

export async function POST(req: NextRequest) {
  const { account } = await createAdminClient()
  const { email, url } = await req.json()

  try {
    const token = await account.createMagicURLToken(ID.unique(), email, url)
    console.log('token', token)
    return Response.json({})
  } catch (error) {
    return Response.json({ error })
  }
}

so your app and appwrite are on the same host?

I am not sure. My app is running on localhost:3000, and I didn't do any setup for Appwrite. Should I do anything on the Appwrite console? Basically, I am trying to follow this tutorial: https://www.youtube.com/watch?v=7LN05c-ov_0&list=WL&index=8&t=549s, and see him demo on localhost
