account scope missing on Google oAuth sign in

I am currently facing an issue which is only happening to one of my testers. When she tries to sign in either with google or using email and password on both her phone and system, it throws an error.

When I run the process on my end and ask others to do it, it works well but when she does it on her end it doesn't work.

Signing up with email and password returns an invalid_parameters error, but it works for other people.

I have tried to replicate it locally and in production but I have not been able to do it.

We checked her cookies and site data but nothing has been set so far so it's clean.

Code for oAuth sign in.

export default function signInWithOAuth(providerName: "facebook" | "google") {
  authAccount.createOAuth2Session(
    providerName,
    `${BASE_URL}/oauth/`,
    `${BASE_URL}/login`
  );
}

BASE_URL = 'https://memora-tau.vercel.app

It works for other user and it's just her. I have tried to find out what's wrong but I don't know

Please create a separate post for the invalid parameters error

The oauth problem is probably a 3rd party cookie problem.

For local development, maybe you can change your browser settings to enable 3rd party cookies.

In production, you'll need to use custom domains

Okay

It's a side project I'm working on so I won't be doing a custom domain. Is there nwi other way?

I hosted the app on Vercel tho

But why does it work for some people and it doesn't work for others

Some people or some browsers are more lenient on 3rd party cookies

Unfortunately not

Hmm, interesting. And the browsers used were chrome

Ah I see. So if I got through with it, once I connect the custom domain it should start working yes?

Yes, assuming this is indeed the problem

Is there something else that could be the problem if not this?

Maybe I can try that since I don't have access to a custom domain
