Experiencing "Invalid verifier" error with Google OAuth in Convex Auth
Experiencing "Invalid verifier" error with Google OAuth in Convex Auth I'm facing an issue where the user session doesn’t persist after a page refresh when using Google OAuth with Convex Auth. The authSessions table remains empty, and I’m seeing an "Invalid verifier" error in the Convex logs. Here’s my Convex backend configuration: Environment Details - @convex-dev/auth: ^0.0.84 - convex: ^1.24.0 - Platform: Web (Next.js with App Router) Convex Backend Configuration (convex/auth.ts) 
import Google from "@auth/core/providers/google";
import { convexAuth } from "@convex-dev/auth/server";

export const { auth, signIn, signOut, store, isAuthenticated } = convexAuth({
  providers: [Google],
});
import Google from "@auth/core/providers/google";
import { convexAuth } from "@convex-dev/auth/server";

export const { auth, signIn, signOut, store, isAuthenticated } = convexAuth({
  providers: [Google],
});
Environment variables (GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET) are set in the Convex dashboard. Middleware (middleware.ts) 
import { convexAuthNextjsMiddleware } from "@convex-dev/auth/nextjs/server";

export default convexAuthNextjsMiddleware(undefined, {
  cookieConfig: { maxAge: 60 * 60 * 24 * 30 },
  verbose: true,
});

export const config = {
  matcher: ["/((?!.*\\..*|_next).*)", "/", "/(api|trpc)(.*)"],
};
import { convexAuthNextjsMiddleware } from "@convex-dev/auth/nextjs/server";

export default convexAuthNextjsMiddleware(undefined, {
  cookieConfig: { maxAge: 60 * 60 * 24 * 30 },
  verbose: true,
});

export const config = {
  matcher: ["/((?!.*\\..*|_next).*)", "/", "/(api|trpc)(.*)"],
};

Is there a solution that works?
