# Google OAuth Integration Verification Report
**Date**: 2025-10-14
**Issue**: OAuth callback previously failing with "User not found"
**Fix**: Migrated user ID from UUID to Clerk ID
**Status**: ✅ **VERIFIED - Ready for End-to-End Testing**
---
## Executive Summary
The Google OAuth integration has been successfully verified at the database level after migrating the user ID from UUID format to Clerk ID format. The OAuth callback will now be able to find the user and store tokens correctly.
### Key Changes
- ✅ User ID migrated from UUID `20f51f5c-1cd6-4b2f-8cb0-b98b57c2b8cf` → Clerk ID `user_33ZB97Sz4n775IAjl8pY5YZHqYd`
- ✅ User lookup by Clerk ID verified working
- ✅ OAuth callback route implementation verified
- ✅ GoogleAuthService `storeTokens()` method uses correct lookup pattern
---
## Verification Tests Completed
### 1. Database State Verification ✅
**Test**: Pre-OAuth database state check
**Command**:
```bash
npx tsx << 'EOF'
import { createClient } from '@libsql/client';
const client = createClient({
url: process.env.TURSO_URL!,
authToken: process.env.TURSO_AUTH_TOKEN!,
});
const user = await client.execute({
sql: 'SELECT id, email, metadata FROM users WHERE id = ?',
args: ['user_33ZB97Sz4n775IAjl8pY5YZHqYd']
});
console.log(user.rows[0]);
await client.close();
EOF
```
**Result**:
```
✅ User found in database
User ID: user_33ZB97Sz4n775IAjl8pY5YZHqYd
Email: bob@matsuoka.com
Current metadata: null
Has Google tokens? No
```
**Status**: ✅ **PASS** - User exists with Clerk ID, no tokens yet (expected)
---
### 2. User Lookup Simulation ✅
**Test**: Simulate OAuth callback user lookup
**Command**:
```bash
npx tsx << 'EOF'
const userById = await client.execute({
sql: 'SELECT * FROM users WHERE id = ?',
args: ['user_33ZB97Sz4n775IAjl8pY5YZHqYd']
});
EOF
```
**Result**:
```
✅ User found by Clerk ID!
User ID: user_33ZB97Sz4n775IAjl8pY5YZHqYd
Email: bob@matsuoka.com
Created at: 2025-09-20T14:49:44.797Z
✅ OAuth callback will be able to store tokens ✓
```
**Cross-check by email**:
```
✅ User found by email!
User ID in database: user_33ZB97Sz4n775IAjl8pY5YZHqYd
Matches Clerk ID? Yes ✓
```
**Status**: ✅ **PASS** - User lookup by Clerk ID works, email cross-check confirms match
---
### 3. OAuth Callback Flow Analysis ✅
**File**: `/web/app/api/auth/google-connect/callback/route.ts`
**Key Logic**:
```typescript
// Line 15: state parameter contains Clerk userId
const state = searchParams.get('state'); // Clerk userId
// Line 56: Store tokens using state (Clerk ID)
const storeResult = await googleAuth.storeTokens(state, tokenResult.data);
```
**GoogleAuthService.storeTokens() implementation** (line 103-138):
```typescript
async storeTokens(userId: string, tokens: GoogleOAuthTokens): Promise<SyncResult<void>> {
try {
// First try email lookup
let user = await this.db.getUserByEmail(userId);
// Then try ID lookup (THIS IS THE KEY FIX)
if (!user) {
user = await this.db.getUserById(userId);
}
if (!user) {
return {
ok: false,
error: {
type: 'VALIDATION_ERROR',
message: `User not found: ${userId}`,
},
};
}
// Update user metadata with tokens
await this.db.updateUser(user.id, {
metadata: {
...(user.metadata || {}),
googleOAuthTokens: tokens,
googleOAuthConnectedAt: new Date().toISOString(),
},
});
return { ok: true, data: undefined };
} catch (error) {
// Error handling...
}
}
```
**Analysis**:
- ✅ OAuth callback passes Clerk ID as `state` parameter
- ✅ `storeTokens()` tries email lookup first (fails - "bob@matsuoka.com" as ID)
- ✅ Falls back to ID lookup with `getUserById(userId)` - **THIS WILL NOW SUCCEED**
- ✅ User found, tokens stored in metadata
- ✅ Redirect to `/settings?google_connected=true`
**Status**: ✅ **PASS** - Logic flow is correct and will work with Clerk ID
---
### 4. OAuth Route Availability ✅
**Routes Verified**:
```
✅ /api/auth/google-connect (OAuth initiation)
✅ /api/auth/google-connect/callback (OAuth callback)
✅ /api/google/status (Connection status check)
```
**Build Output**:
```
Route (app) Size First Load JS
├ ƒ /api/auth/google-connect
├ ƒ /api/auth/google-connect/callback
├ ƒ /api/google/status
```
**Status**: ✅ **PASS** - All required routes are built and available
---
## Previous Failure Analysis
### What Was Broken
**Problem**: OAuth callback failed with "User not found"
**Root Cause**:
```typescript
// OAuth callback passed Clerk ID:
const state = 'user_33ZB97Sz4n775IAjl8pY5YZHqYd';
// storeTokens() tried to find user:
let user = await this.db.getUserByEmail('user_33ZB97Sz4n775IAjl8pY5YZHqYd'); // Failed
user = await this.db.getUserById('user_33ZB97Sz4n775IAjl8pY5YZHqYd'); // Failed!
// Database had UUID instead:
users table: id = '20f51f5c-1cd6-4b2f-8cb0-b98b57c2b8cf'
```
**Why It Failed**:
- Clerk ID `user_33ZB97Sz4n775IAjl8pY5YZHqYd` didn't match UUID `20f51f5c-...`
- `getUserById()` lookup failed
- OAuth callback returned error: `token_storage_failed`
### What Was Fixed
**Solution**: Migrate user ID to match Clerk ID
```sql
-- Migration executed:
UPDATE users
SET id = 'user_33ZB97Sz4n775IAjl8pY5YZHqYd'
WHERE email = 'bob@matsuoka.com';
-- Result:
SELECT id FROM users WHERE email = 'bob@matsuoka.com';
-- Returns: user_33ZB97Sz4n775IAjl8pY5YZHqYd ✓
```
**Now OAuth Flow Works**:
1. User clicks "Connect Google Account"
2. Redirected to Google with state=`user_33ZB97Sz4n775IAjl8pY5YZHqYd`
3. User grants permissions
4. Callback receives state=`user_33ZB97Sz4n775IAjl8pY5YZHqYd`
5. `storeTokens('user_33ZB97Sz4n775IAjl8pY5YZHqYd', tokens)` called
6. `getUserById('user_33ZB97Sz4n775IAjl8pY5YZHqYd')` → **FINDS USER** ✅
7. Tokens stored in user.metadata ✅
8. Redirect to `/settings?google_connected=true` ✅
---
## End-to-End Test Plan
### Prerequisites
- ✅ Web server running on port 3002
- ✅ User authenticated with Clerk
- ✅ Google OAuth credentials configured
- ✅ Database user migrated to Clerk ID
### Test Steps
1. **Navigate to Settings**
```
http://localhost:3002/settings
```
2. **Initiate OAuth**
- Click "Connect Google Account" button
- Should redirect to Google OAuth consent screen
3. **Grant Permissions**
- Sign in to Google account (bob@matsuoka.com)
- Review and accept permissions:
- Google Contacts (read/write)
- Google Calendar (read)
- Gmail (read)
- Click "Allow"
4. **Verify Redirect**
- Should redirect to: `http://localhost:3002/settings?google_connected=true`
- Status should show "Connected" with green indicator
5. **Verify Token Storage**
```bash
cd /Users/masa/Projects/mcp-memory-ts
npx tsx /tmp/check-tokens-after-oauth.ts
```
**Expected Output**:
```
✅✅✅ SUCCESS! Google OAuth tokens stored!
Token details:
- Connected at: 2025-10-14T...
- Has access_token? Yes ✓
- Has refresh_token? Yes ✓
- Token type: Bearer
- Expires at: ...
```
6. **Test Google Integration**
```bash
# Check connection status
mcp-memory google auth --user-email bob@matsuoka.com
# Test contacts sync
mcp-memory google contacts-sync --user-email bob@matsuoka.com --direction import --dry-run
# Test calendar sync
mcp-memory google calendar-sync --user-email bob@matsuoka.com
```
---
## Success Criteria
All criteria must be met for OAuth integration to be considered fully functional:
- ✅ **Database**: User exists with Clerk ID
- ✅ **Lookup**: User can be found by Clerk ID
- ✅ **Routes**: OAuth endpoints are available
- ✅ **Logic**: OAuth callback uses correct user lookup
- ⏳ **E2E Test**: Full OAuth flow completes successfully (pending user test)
- ⏳ **Token Storage**: Tokens persist in user metadata (pending user test)
- ⏳ **Sync Test**: Google APIs work with stored tokens (pending user test)
---
## Monitoring Commands
### Before OAuth Flow
```bash
# Check current state
npx tsx << 'EOF'
import { createClient } from '@libsql/client';
const client = createClient({
url: process.env.TURSO_URL!,
authToken: process.env.TURSO_AUTH_TOKEN!,
});
const user = await client.execute({
sql: 'SELECT id, email, metadata FROM users WHERE id = ?',
args: ['user_33ZB97Sz4n775IAjl8pY5YZHqYd']
});
console.log('User:', user.rows[0]);
await client.close();
EOF
```
### During OAuth Flow
```bash
# Monitor logs in real-time
pm2 logs mcp-memory-web-3002 --lines 0
```
### After OAuth Flow
```bash
# Verify token storage
npx tsx /tmp/check-tokens-after-oauth.ts
```
---
## Troubleshooting
### Issue: "User not found" still occurs
**Diagnosis**:
```bash
# Verify user ID in database
npx tsx -e "
import { createClient } from '@libsql/client';
const client = createClient({url: process.env.TURSO_URL!, authToken: process.env.TURSO_AUTH_TOKEN!});
const result = await client.execute({sql: 'SELECT id FROM users WHERE email = ?', args: ['bob@matsuoka.com']});
console.log('User ID:', result.rows[0]?.id);
await client.close();
"
```
**Expected**: `user_33ZB97Sz4n775IAjl8pY5YZHqYd`
**If different**: User ID not migrated correctly, re-run migration
### Issue: OAuth callback fails with different error
**Check logs**:
```bash
pm2 logs mcp-memory-web-3002 --lines 100 | grep -i "google\|oauth\|error"
```
**Common errors**:
- `token_exchange_failed`: Invalid OAuth code or Google API issue
- `token_storage_failed`: Database write failed (check logs)
- `invalid_callback`: Missing code or state parameter
### Issue: Tokens stored but sync fails
**Verify tokens**:
```bash
mcp-memory google auth --user-email bob@matsuoka.com
```
**If token expired**:
- OAuth should auto-refresh using refresh_token
- Check Google API quotas and rate limits
- Verify scopes granted match requested scopes

## Next Steps
1. **User Testing**: Follow test plan in [OAUTH_TEST_INSTRUCTIONS.md](./OAUTH_TEST_INSTRUCTIONS.md)
2. **Verify Success**: Run post-OAuth verification script
3. **Test Sync**: Verify Google Contacts and Calendar sync work
4. **Monitor**: Watch for any errors in production logs
5. **Document**: Update this report with test results

## Files Modified
1. **Database**: `users` table - ID migrated to Clerk ID
2. **No code changes needed**: Existing OAuth logic already correct
