i want to get errors from next auth when user signs in with oauth
register the signin page as an error page inside your NextAuth configuration and then get the error from the URL parameter
jaunty peak
Can you share your NextAuth config please?

next/router doesnt work in new nextjs
jaunty peak
Yeah, use next/navigation instead
orchid flame
because when you sign in google
its redirected to google page then from google page
redirected to some link like /api/auth/providers/google
i dont remember
jaunty peak
That's fine so far
It gets a token from Google, then uses that token to get the user data in the callback
orchid flame
i dont understand why signIn function doesnt have error handler itself
yes ans as we see in network page it actually gets this error in url
orchid flame
okay
jaunty peak
What does await redirectIfAuthenticated(); do?
orchid flame
export async function redirectIfAuthenticated() {
const session = await getServerSession(authOptions);
session && redirect("/");
}```Can you comment that line out and test?
Because something is redirecting you
And that is why you are not getting passed the URL parameters
orchid flame
yes and its same

import Link from "next/link";
import LoginForm from "./form";

And you can see in the response headers that it redirects you without parameters
So seems the be the localization
Can you show me how that's implemented?
orchid flame
import { NextRequest, NextResponse } from "next/server";
import { match } from "@formatjs/intl-localematcher";
import Negotiator from "negotiator";
import { defaultLocale, locales } from "./locals";
function getLocale(request: NextRequest) {
const headers = new Headers(request.headers);
const acceptLanguage = headers.get("accept-language");
if (acceptLanguage) {
headers.set("accept-language", acceptLanguage.replaceAll("_", "-"));
}
const headersObject = Object.fromEntries(headers.entries());
const languages = new Negotiator({
headers: headersObject,
}).languages();
return match(languages, locales, defaultLocale);
}
export function middleware(request: NextRequest) {
const pathname = request.nextUrl.pathname;
const pathnameIsMissingLocale = locales.every(
(locale) => !pathname.startsWith(`/${locale}/`) && pathname !== `/${locale}`
);
if (pathnameIsMissingLocale) {
const locale = getLocale(request);
return NextResponse.redirect(
new URL(`/${locale}/${pathname}`, request.url)
);
}
}
export const config = {
matcher: ["/((?!_next|api|favicon.ico).*)"],
};
Alright, one sec
jaunty peak
```js
import { NextRequest, NextResponse } from "next/server";
import { match } ...
So the issue is that pathname does not include URL parameters. So when redirecting the user to their locale, your middleware dumps all query parameters.
To fix this, make the following changes in your middleware function:
// add this line where you also define your `pathname` variable:
const searchParams = request.nextUrl.search;
// edit your redirect line like this:
return NextResponse.redirect(
new URL(`/${locale + pathname + searchParams}`, request.url);
);
Here's a screenshot of the structure of the request.nextUrl object to better understand why this error occurred and how we fix it

jaunty peak
why is there
Oh, btw the two slashes are there because pathname already includes a slash. I edited my answer accordingly
orchid flame
okay
and i have one question if you have time
const errors = {
Signin: "Try signing with a different account.",
OAuthSignin: "Try signing with a different account.",
OAuthCallback: "Try signing with a different account.",
OAuthCreateAccount: "Try signing with a different account.",
EmailCreateAccount: "Try signing with a different account.",
Callback: "Try signing with a different account.",
OAuthAccountNotLinked:
"To confirm your identity, sign in with the same account you used originally.",
EmailSignin: "Check your email address.",
CredentialsSignin:
"Sign in failed. Check the details you provided are correct.",
default: "Unable to sign in.",
};
const SignInError = ({ error }: any) => {
const errorMessage =
error && (errors[error as keyof typeof errors] ?? errors.default);
return <div className="text-red-500">{errorMessage}</div>;
};```is this right way?
jaunty peak
It's not a wrong way so you should be fine using this
