Hi <:vmathi:812484657547313212> How are you using Supabase in your project? Is it a NextJS project, a Svelte project, React.... ? <@542546860297158656>

I am trying supabase for the first time, haven't done anything in terms of the DB and just wanted to add Auth for now.

hmm, do you have this same issue when you add a password field?

my code is basically the exact same as the tutorial

Be sure in the "Authentification" > "Settings" tab you have ``http://localhost:3000`` for the ``site url`` field

the error that comes back is simply `Request Failed`

Alright so in that case, i suppose it comes from the instance itself. I already got this issue too, and i just created a new instance. Can you try with another instance and tell me if it fixes the issue?

Unfortunately yes. I call this kind of supabase instances "a cursed instance" xD

because the instance has an issue, and not your code

haven't done anything with the DB at all yet so its no issue :0

hey so that managed to work! thanks for your help!

once someone signs in via magic link w just their email

they are issued a JWT right? for an hour?

how do i listen for whether their JWT is still active and how to renew it?

hmm, there is no event in my knowledge to listen the jwt token change. But, you can listen for an auth change i guess: https://supabase.com/docs/reference/javascript/auth-onauthstatechange

so does the token refresh happen by itself?

and would you just stick that onAuthStateChange inside a useEffect for react? sorry kind of a dumb question

If you are using supbase-js it refreshes the token for you.  You can monitor onAuthStateChange and you will see the refresh event.

<@542546860297158656> yes, you would put it in an useEffect, see the example here: https://github.com/supabase/supabase/blob/master/examples/user-management/react-user-management/src/App.js#L13-L16
