    I think you might have a bad link inside the createSupabase function

    Hey guys, I'm using Supabase Auth with Next.js This is what my API register function looks like...
    Copy code
    javascript
export default async function handler(req, res) {

        const { username, email, password } = req.body;

        let { user, error } = await supabase.auth.signUp({
            email: email,
            password: password,
        });

        if (!error) {
            res.status(201).json({ data: user, message: "Signed Up!" });
        }
}
    I want the user I get from the signUp function to be stored in a cookie so that I can get the user from cookie in a different endpoint using
    Copy code
    supabase.auth.api.getUserByCookie

    Hi, I think that before you return a 201 you can add this line:
    Copy code
    supabase.auth.api.setAuthCookie(req)
  • z
    I get this error
  • r
    You should add
    Copy code
    event: 'SIGNED_IN
    in the request body and probably the user too
  • z
    okay
  • z
    didn't get the second part I added 'event' to the request body
  • r
    In the request body you have to add the sign in event and and the user as a session like this and I think this should work
    Copy code
    { event: 'SIGNED_IN', session: user }
  • z
    Where do I get the user for the session
  • z
    Copy code
    javascript
let user = {
            email: email,
            password: password,
            event: "SIGNED_IN",
        };
  • r
    From the sign in function
  • z
    I'm sorry could you demonstrate the code once? 😓
  • r
    No problem 🙂
    Copy code
    export default async function handler(req, res) {

    const { username, email, password } = req.body;

    let { user, error } = await supabase.auth.signUp({
        email: email,
        password: password,
    });

    if (!error) {
        req.body.event = 'SIGNED_IN'
        req.body.session = user;

        await supabase.auth.api.setAuthCookie(req, res)
        res.status(201).json({ data: user, message: "Signed Up!" });
    }
}
  • z
    got it
  • r
    Is it working now ?
  • z
    😦
  • r
    Try by adding res as second parameter of the setAuthCookie function (i edited my previous message)
  • z
    Didn't get an error on the client side but I got this
  • z
    Copy code
    Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client
  • z
    on the server
  • r
    Arf I can't help you on the server side ..
  • z
    I see
  • z
    thanks man
  • t
    yeah im using a form

    i'm trying to get signin/signup working in a project with React. On sign in, I'm getting an error saying "You must provide either an email, phone number or a third-party provider." when i enter in a valid email. My current code reads as the following for signin```javascript const signin = async (username, password, history) => { console.log("log in called", username, password) try { const {error} = await supabase.auth.signIn({username, password}) if (error) throw error alert('logged in') console.log('logged in') window.location.href = '/dashboard'; // history.push('/dashboard') } catch (error) { alert(error.message) } } ``` - would you know what's causing this error? (the console log is printing the expected output too). My code for signup is structured similarly, except it calls 
    signUp
    instead. When signup is called, I'm getting no output in the console, and the page just reloads. Would you know what's causing that/how I could go about fixing/debugging this?
  • k
    would i say something like 
    const {access_token, error} = await supabase.auth.signIn({username, password})
    ?
  • s
    The property is 
    email
    , not 
    username
  • k
    but that's just a case of variable names right? (changing username to email doesn't/shouldn't change anything)
  • s
    They're calling 
    signIn({ username, password })
    and the error is telling them to provide a valid email, so changing that to 
    signIn({ email: username, password })
    should fix it
  • k
    thanks, that fixed it!
