Describe the issue

cannot sign in using Line provider line returns

http://localhost:3000/api/auth/callback/line?error=INVALID_REQUEST&error_description=%27state%27+is+not+specified.

How to reproduce

ENVs

AUTH_LINE_ID=xxx
AUTH_LINE_SECRET=xxx
This in V5 does not work

import NextAuth from "next-auth";
import Google from "@auth/core/providers/google";
import LINE from "@auth/core/providers/line";

export const {
handlers: { GET, POST },
auth,
} = NextAuth({
providers: [Google, LINE]
})
While the same ID and Secret work fine in V4.
Feeding ID and secret directly also does not work

export const {
handlers: { GET, POST },
auth,
} = NextAuth({
providers: [LINE({ clientId: LINE_CLIENT_ID, clientSecret: LINE_CLIENT_SECRET })
...

Expected behavior

can sign in using line provider

I had a look at this and to get it working you need to add checks: ["state"] when adding the LINE provider.

   Line({
     clientId: process.env.LINE_CLIENT_ID,
     clientSecret: process.env.LINE_CLIENT_SECRET,
     checks: ["state"],
   })

Confirmed working solution

Can confirm this fixes the Line provider login, Still curious what is the cause
