How to work with auth-proxy in previews and test function locally

[vadimshvetsov]

Hey,

I've tried to deploy auth-proxy with zero config and can't make it works, all envs set correctly according to the README, custom domain added but doesn't work even locally.

I was trying to debug locally and propagated my env using with-env script and still can't match the action.

From Vercel logs:

�[31m[auth][error]�[0m UnknownAction: Cannot parse action at /callback/google. Read more at https://errors.authjs.dev#unknownaction

From localhost logs:

[auth][error] UnknownAction: Cannot parse action at /callback/google. Read more at https://errors.authjs.dev#unknownaction at parseActionAndProviderId

My auth-proxy/routes/[...auth].ts:

import { Auth } from "@auth/core"
import Google from "@auth/core/providers/google"
import Resend from "@auth/core/providers/resend"
import { eventHandler, toWebRequest } from "h3"

export default eventHandler(async (event) =>
  Auth(toWebRequest(event), {
    secret: process.env.AUTH_SECRET,
    trustHost: true,
    redirectProxyUrl: process.env.AUTH_REDIRECT_PROXY_URL,
    providers: [
      Google({
        clientId: process.env.GOOGLE_ID,
        clientSecret: process.env.GOOGLE_SECRET,
      }),
      Resend({
        apiKey: process.env.AUTH_RESEND_KEY,
      }),
    ],
  }),
)

Appreciate any help.

Try updating to the current state. I added a base path which seems to have resolved some issues

Thanks, after update it works. Appreciate your efforts 🙏

Hi @vadimshvetsov How did to run auth-proxy locally? I'm using a GoogeProvider and CredentialsProvider.
Can't run pnpm dev from auth-proxy. the script is available in my auth-proxy/package.json

[vadimshvetsov]

I didn't try to run it locally, the main point is to run it on the remote server to have stable url for providers

[juliusmarminge]

Yea the proxy has no use locally. You want that on a server somewhere with a stable URL

Signing from expo open nextjs/login page and then i see a 303 in the console, then nothing else happen.

Is there a way to write my my own expo/login page and then call the auth-proxy with the credentials ?
Currently it opens a browser. Not a good user experience IMO

Hi. I was unable to deploy next-auth in vercel. This is what i get

Build Failed
The file "/vercel/path0/apps/auth-proxy/.output/routes-manifest.json" couldn't be found. This is often caused by a misconfiguration in your project.

Build command: turbo run build

Did you set the NITRO_PRESET variable? https://nitro.unjs.io/deploy/providers/vercel#vercel-edge-functions

[jpainam]

I did, i set it to NITRO_PRESET="vercel_edge"
