Is this suited for github?

  • Yes, this is suited for github

To Reproduce

the docs at
https://www.better-auth.com/docs/integrations/tanstack
state that the middleware gets a request object, which is no longer true

import { redirect } from "@tanstack/react-router";
import { createMiddleware } from "@tanstack/react-start";
import { auth } from "./auth";

export const authMiddleware = createMiddleware().server(
    async ({ next, request }) => {
        const session = await auth.api.getSession({ headers: request.headers })

        if (!session) {
            throw redirect({ to: "/login" })
        }

        return await next()
    }
);

Current vs. Expected behavior

instead you need to use `

import {
  getRequestHeaders,
} from '@tanstack/react-start/server'
...
        const session = await auth.api.getSession({ headers: getRequestHeaders() })

What version of Better Auth are you using?

N/A (live docs)

@better-auth-agent[bot] commented on GitHub (Dec 17, 2025):

Thanks for raising this issue! It looks like the documentation is currently still showing the old approach of getting headers directly from the request object. With the current version, you should call getRequestHeaders() from @tanstack/react-start/server to correctly retrieve the headers when checking the session. Could you confirm that updating your middleware to use getRequestHeaders() resolves the problem? Tag @better-auth-agent if you would like an answer from the Agent. What other integrations or changes have you noticed that might need updated guidance?

If you need more help, tag @better-auth-agent in a comment so I can respond.
