[magicLink - drizzleAdapter] The \"payload\" argument must be of type object. Received null

Hey guys, I am struggling to get to the bottom of this issue. I am hosting my backend with

open-next

open-next

open-next

open-next

THis means that it's hosted in a lambda which shouldn't affect anything - My other DB functions work just fine.

All envvars exist

My implementation works locally.
My hosted database connection works as expected in other parts of my app

This error is haunting me. Any tips for how I can debug it?

None of the logs defined below get triggered which is weird.

secret: process.env.BETTER_AUTH_SECRET,

    trustedOrigins: [getServerUrl(), '*'],
    onAPIError: {

      onError(e, context) {
        console.error("[BETTER_AUTH - ERROR]", e);
        console.error("[BETTER_AUTH - CONTEXT]", context);
      }
    },

I am using this better-auth version: "better-auth": "1.2.3",

Any ideas? Am I missing something?

---

Here is my /api/auth/[...all] route

The reason I have a

getBetterAuth

getBetterAuth

getBetterAuth

getBetterAuth is because I am hosting on opennext & get + set the environment variables at runtime (for security purposes), so hence the reason for a function that will getBetterAuth WHEN it's needed. NOTE: I only initialize the client once, if exists, use existing, else create new client.

import { getBetterAuth } from "@/lib/auth/better-auth"; // path to your auth file
import { toNextJsHandler } from "better-auth/next-js";

export const POST = (req: Request) => {
  return toNextJsHandler(getBetterAuth()).POST(req);
};


export const GET = (req: Request) => {
return toNextJsHandler(getBetterAuth()).GET(req);
};

import { getBetterAuth } from "@/lib/auth/better-auth"; // path to your auth file
import { toNextJsHandler } from "better-auth/next-js";

export const POST = (req: Request) => {
  return toNextJsHandler(getBetterAuth()).POST(req);
};


export const GET = (req: Request) => {
return toNextJsHandler(getBetterAuth()).GET(req);
};

import { getBetterAuth } from "@/lib/auth/better-auth"; // path to your auth file
import { toNextJsHandler } from "better-auth/next-js";

export const POST = (req: Request) => {
  return toNextJsHandler(getBetterAuth()).POST(req);
};


export const GET = (req: Request) => {
return toNextJsHandler(getBetterAuth()).GET(req);
};

import { getBetterAuth } from "@/lib/auth/better-auth"; // path to your auth file
import { toNextJsHandler } from "better-auth/next-js";

export const POST = (req: Request) => {
  return toNextJsHandler(getBetterAuth()).POST(req);
};


export const GET = (req: Request) => {
return toNextJsHandler(getBetterAuth()).GET(req);
};
