getAuthUserId() Returns Null Despite Successful OAuth Sign-In

getAuthUserId() Returns Null Despite Successful OAuth Sign-In Issue: getAuthUserId(ctx) returns null in all backend queries/mutations, even though OAuth sign-in succeeds and creates a valid session. Environment: - @convex-dev/auth: ^0.0.90 - Auth provider: Google OAuth What Works: - ✅ OAuth sign-in completes - ✅ Session created in authSessions table - ✅ JWT stored in browser localStorage What Doesn't Work: - ❌ getAuthUserId(ctx) returns null - ❌ ctx.auth._token is undefined (JWT not sent with requests) Code: Frontend (with useConvexAuth): 
const { isAuthenticated, isLoading } = useConvexAuth();
const userProfile = useQuery(api.users.getCurrentUserProfile, isAuthenticated ? {} : "skip");
const { isAuthenticated, isLoading } = useConvexAuth();
const userProfile = useQuery(api.users.getCurrentUserProfile, isAuthenticated ? {} : "skip");
Backend: 
export const getCurrentUserProfile = query({
  handler: async (ctx) => {
    const userId = await getAuthUserId(ctx);  // Returns null!
    if (userId === null) return null;
    return await ctx.db.get(userId);
  },
});
export const getCurrentUserProfile = query({
  handler: async (ctx) => {
    const userId = await getAuthUserId(ctx);  // Returns null!
    if (userId === null) return null;
    return await ctx.db.get(userId);
  },
});
Logs: 
[createOrUpdateUser] Returning user ID: 'k578y1k2dpbn09n6d3m725hcfs7tcx0f' ✅
[auth:store] type: verifyCodeAndSignIn ✅
[getCurrentUserProfile] userId: null ❌

What We've Tried: - Implemented useConvexAuth() to wait for isAuthenticated: true before calling queries - Verified JWT exists in localStorage - Cleared all sessions and signed in fresh multiple times - Used getAuthUserId() from @convex-dev/auth/server Our auth.config.ts has domain: process.env.CONVEX_SITE_URL which may be undefined. Could this be blocking JWT validation? How should we properly configure authentication?

If isAuthenticated from useConvexAuth is true, jwt validation is working - you should see Authentication messages in the sync websocket connection with a jwt. If you have a minimal repro I can take a look.

Minimal Reproduction Files 1. convex/auth.config.ts: 
export default {
  providers: [
    {
      domain: process.env.CONVEX_SITE_URL,
      applicationID: "convex",
    },
  ],
};
export default {
  providers: [
    {
      domain: process.env.CONVEX_SITE_URL,
      applicationID: "convex",
    },
  ],
};
2. convex/auth.js: 
import { convexAuth } from "@convex-dev/auth/server";
import Google from "@auth/core/providers/google";

export const { auth, signIn, signOut, store } = convexAuth({
  providers: [Google],
  callbacks: {
    async createOrUpdateUser(ctx, args) {
      const email = args.profile?.email;
      const user = await ctx.db.query("users").withIndex("email", (q) => q.eq("email", email)).first();
      console.log("[createOrUpdateUser] Returning user ID:", user?._id);
      return user._id;
    },
  },
});
import { convexAuth } from "@convex-dev/auth/server";
import Google from "@auth/core/providers/google";

export const { auth, signIn, signOut, store } = convexAuth({
  providers: [Google],
  callbacks: {
    async createOrUpdateUser(ctx, args) {
      const email = args.profile?.email;
      const user = await ctx.db.query("users").withIndex("email", (q) => q.eq("email", email)).first();
      console.log("[createOrUpdateUser] Returning user ID:", user?._id);
      return user._id;
    },
  },
});
3. convex/users.ts (query): 
import { getAuthUserId } from "@convex-dev/auth/server";
import { query } from "./_generated/server";

export const getCurrentUserProfile = query({
  handler: async (ctx) => {
    const userId = await getAuthUserId(ctx);
    console.log("[getCurrentUserProfile] userId:", userId);
    if (userId === null) return null;
    return await ctx.db.get(userId);
  },
});
import { getAuthUserId } from "@convex-dev/auth/server";
import { query } from "./_generated/server";

export const getCurrentUserProfile = query({
  handler: async (ctx) => {
    const userId = await getAuthUserId(ctx);
    console.log("[getCurrentUserProfile] userId:", userId);
    if (userId === null) return null;
    return await ctx.db.get(userId);
  },
});
4. Frontend: AuthContext.jsx (React): 
import { useConvexAuth } from "@convex-dev/auth/react";
import { useQuery } from "convex/react";

export function AuthProvider({ children }) {
  const { isAuthenticated, isLoading } = useConvexAuth();
  console.log("isAuthenticated:", isAuthenticated, "isLoading:", isLoading);
  
  const userProfile = useQuery(
    api.users.getCurrentUserProfile,
    isAuthenticated ? {} : "skip"
  );
  
  console.log("userProfile:", userProfile);
  // ... rest of component
}
import { useConvexAuth } from "@convex-dev/auth/react";
import { useQuery } from "convex/react";

export function AuthProvider({ children }) {
  const { isAuthenticated, isLoading } = useConvexAuth();
  console.log("isAuthenticated:", isAuthenticated, "isLoading:", isLoading);
  
  const userProfile = useQuery(
    api.users.getCurrentUserProfile,
    isAuthenticated ? {} : "skip"
  );
  
  console.log("userProfile:", userProfile);
  // ... rest of component
}
Observed Behavior: - isAuthenticated: true after sign-in ✅ - [createOrUpdateUser] logs show correct user ID ✅ - [getCurrentUserProfile] userId: null ❌ - JWT exists in localStorage ✅ @erquhart I don't know if this helps to repro.
