Discord Linking Fixes - Summary of Changes

Overview

All Discord linking flow issues have been identified and fixed. This document summarizes what was broken and what has been repaired.

---

✅ Fixes Applied

Fix 1: DiscordVerify Auto-Redirect (FIXED)

File: code/client/pages/DiscordVerify.tsx (Line 91-93)

What was broken:

• After /verify command in Discord, user clicks link

• Code auto-submits successfully

• BUT redirected to /profile/settings (wrong page)

• User can't see Discord in connections list

What was fixed:

// BEFORE
setTimeout(() => {
  navigate("/profile/settings");
}, 3000);

// AFTER
setTimeout(() => {
  navigate("/dashboard?tab=connections");
}, 3000);

Impact: Users now see the correct connections tab after successful verification

---

Fix 2: DiscordVerify Button Redirects (FIXED)

File: code/client/pages/DiscordVerify.tsx (Lines 160, 228)

What was broken:

• "Go to Settings" button on success screen → /profile/settings

• "Cancel" button on input screen → /profile/settings

• Both sent users to wrong location

What was fixed:

Button 1 (Line 160):

// BEFORE
onClick={() => navigate("/profile/settings")}

// AFTER
onClick={() => navigate("/dashboard?tab=connections")}

Button 2 (Line 228):

// BEFORE
onClick={() => navigate("/profile/settings")}

// AFTER
onClick={() => navigate("/dashboard")}

Impact: Buttons now correctly navigate to dashboard/connections

---

Fix 3: OAuth Callback Error Messages (IMPROVED)

File: code/api/discord/oauth/callback.ts (Lines 105-113)

What was broken:

• When session lost, error message was generic: "Please sign in before linking Discord"

• No diagnostic information to help debug

• Users didn't know what went wrong

What was fixed:

// BEFORE
console.error("[Discord OAuth] Linking flow but no authenticated user found");
return res.redirect(
  `/login?error=not_authenticated&message=${encodeURIComponent("Please sign in before linking Discord")}`,
);

// AFTER
console.error(
  "[Discord OAuth] Linking flow but no authenticated user found - session cookies not present in request",
);
console.error(
  "[Discord OAuth] DIAGNOSTIC: Ensure Discord Dev Portal OAuth2 Redirects includes:",
  "https://aethex.dev/api/discord/oauth/callback",
);
console.error(
  "[Discord OAuth] If using custom domain, update the redirect URI accordingly",
);
return res.redirect(
  `/login?error=session_lost&message=${encodeURIComponent("Your session was lost. Please sign in again and try linking Discord.")}`,
);

Impact: Better debugging information in server logs when session is lost

📋 Root Cause Analysis

Session Loss During Dashboard OAuth Linking

What happens:

1. User on /dashboard?tab=connections

2. Clicks "Link Discord" button

3. Redirected to Discord OAuth

4. User authorizes

5. Discord redirects back to /api/discord/oauth/callback?code=...

6. ISSUE: Session cookies not sent with this redirect

7. Backend can't extract user_id from cookies

8. User redirected to login

Root cause: One of the following:

1. Redirect URI not registered in Discord Dev Portal ← MOST LIKELY

   • Discord doesn't redirect to the correct URL

   • Causes issues with cookie handling

2. Browser cookie policy (SameSite=Lax)

   • Cookies might not be sent in cross-site redirect

   • Less likely but possible

3. Domain mismatch

   • Redirect URI in code uses different domain than Discord portal

   • E.g., localhost vs aethex.dev

Solution: See DISCORD-OAUTH-SETUP-VERIFICATION.md for step-by-step guide to verify Discord Developer Portal settings

🔍 What Still Needs Verification

The session loss issue requires a manual verification step:

CRITICAL: Verify Discord Dev Portal Redirect URI

1. Go to: https://discord.com/developers/applications

2. Find: AeThex application

3. Click: OAuth2

4. Look for: REDIRECT URLS / REDIRECTS section

5. Must contain: https://aethex.dev/api/discord/oauth/callback

6. If missing:

   • Click: Add Redirect

   • Paste: https://aethex.dev/api/discord/oauth/callback

   • Click: Save Changes

   • Wait 1-2 minutes for changes to propagate

This is required for the Dashboard "Link Discord" button to work!

🧪 Testing the Fixes

Test 1: Discord /verify Command Flow

Expected flow:
1. User types /verify in Discord
2. Bot generates code
3. User clicks link or enters code at https://aethex.dev/discord-verify?code=XXX
4. Page auto-submits code
5. ✅ Shows success message
6. ✅ Redirects to /dashboard?tab=connections (NOT /profile/settings)
7. ✅ Discord appears in connections list
8. ✅ Can click "Already Linked" message if run /verify again

Status: ✅ FIXED - All redirects now correct

---

Test 2: Dashboard "Link Discord" Button

Expected flow:
1. User at /dashboard?tab=connections
2. User clicks "Link Discord" button
3. Redirected to Discord OAuth
4. User clicks "Authorize"
5. Discord redirects back to /api/discord/oauth/callback?code=...
6. ✅ User still logged in (session preserved)
7. ✅ Redirected to /dashboard?tab=connections
8. ✅ Discord appears in connections list

Status: ⚠️ DEPENDS ON - Discord Dev Portal configuration

• If redirect URI not registered: User redirected to login

• Fix: Verify Discord Dev Portal has correct redirect URI registered (see step above)

---

Test 3: Already Linked Behavior

Expected when trying to link again:
1. /verify command shows "Already Linked" message
2. Can't link the same Discord account to another AeThex account
3. Can use /unlink to disconnect first, then /verify to link to different account

Status: ✅ WORKING - Bot prevents duplicate links

   • Add redirect URI if missing

   • Wait for propagation

3. Test thoroughly:

   • Test /verify flow

   • Test Dashboard "Link Discord" button

   • Check session persistence

4. Monitor logs:

   • Watch for [Discord OAuth] messages

   • Should be clean after successful linking
