Auth not working

[pnandha]

Hey Fantastic job with the repo.

However when the email returns a link and I click it, it doesn't seem to authenticate.

Any Ideas ? I see the code in the URL but then nothing happens.

The return URL doesn't look correct. It should be going to /auth/callback

You can see the associated code here: https://github.com/KolbySisk/next-supabase-stripe-starter/blob/main/src/app/(auth)/auth/callback/route.ts

And this is where it redirects to that route: https://github.com/KolbySisk/next-supabase-stripe-starter/blob/main/src/app/(auth)/auth-actions.ts

Try updating your redirect URL in Supabase to include http://localhost:3000/auth/callback

Let me know if you get it working

Hi there @KolbySisk, I am running into this issue as well. I'm relatively new to Supabase auth so I am trying to figure this out as well. Is this how the Supabase URL needs to be set up?

When clicking this link now from my email it takes me to my Vercel URL, not my localhost. However when I head back to localhost it recognizes me as logged in.

This fixes this for me for now but would ultimately want to make sure I have this set up correctly in the long haul. Happy to help with documentation, code comments, or anything else to help newbies getting up and running with this.

@pnandha I think I figured this out. I needed to set the NEXT_PUBLIC_SITE_URL in my .env.local to http://localhost:3000. This set the authActions.js file with all the helpers in it to use getUrl correctly to properly set /auth/callback to work as the redirect.

@RobErskine Happy to hear you figured it out.

I see the problem now. The redirect uses the getURL util function which looks for the NEXT_PUBLIC_SITE_URL and when not found falls back to localhost:3000. The intention here was that this var wouldn't be set locally and so it would always fall back.

But I merged this PR: #3 which sets the NEXT_PUBLIC_SITE_URL to a bad default. I should have paid closer attention. I think an easy fix here is to set the var to localhost:3000 locally.

Thanks for the help.
