Quick guide to resolve common connector issues with authentication, syncing, and permissions.

​
Quick Health Check

Check if your connectors are working properly: 
const connections = await client.connections.list({
  containerTags: ['user-123']
});

connections.forEach(conn => {
  console.log(`${conn.provider}: ${conn.email} - Connected ${conn.createdAt}`);
});

// Check for stuck documents
const documents = await client.connections.listDocuments('notion', {
  containerTags: ['user-123']
});

const failed = documents.filter(doc => doc.status === 'failed');
if (failed.length > 0) {
  console.log(`⚠️ ${failed.length} documents failed to sync`);
}

Common Issues

​
OAuth Callback Fails

Problem: “Invalid redirect URI” error after user grants permissions Solution: Ensure your redirect URL matches EXACTLY what’s configured in your OAuth app: 
// correct - exact match with OAuth app settings
const connection = await client.connections.create('notion', {
  redirectUrl: 'https://yourapp.com/auth/notion/callback',
  containerTags: ['user-123']
});

// Wrong - URL doesn't match
// redirectUrl: 'https://yourapp.com/callback'
Prevention:
  • Use HTTPS for production URLs
  • Copy the exact URL from your OAuth app settings
  • Test the flow in development first

​
Documents Not Syncing

Problem: Documents stuck in “queued” or “extracting” status for over 30 minutes Solution: Trigger a manual sync: 
// Force sync for stuck documents
await client.connections.import('notion', {
  containerTags: ['user-123']
});
If documents consistently fail:
  • Check if files are over 50MB (may timeout)
  • Verify you have permission to access the documents
  • Ensure the document type is supported

​
Permission Denied Errors

Problem: Some documents show “permission denied” or aren’t syncing Solution: Re-authenticate with proper permissions: 
// Delete and recreate connection
await client.connections.deleteByProvider('google-drive', {
  containerTags: ['user-123']
});

const newConnection = await client.connections.create('google-drive', {
  redirectUrl: 'https://yourapp.com/callback',
  containerTags: ['user-123']
});

// User must re-authenticate
window.location.href = newConnection.authLink;

​
Sync Takes Too Long

Problem: Hundreds of documents taking hours to sync Solution: Set reasonable document limits: 
const connection = await client.connections.create('onedrive', {
  redirectUrl: 'https://yourapp.com/callback',
  containerTags: ['user-123'],
  documentLimit: 500  // Start with fewer documents
});

​
Provider-Specific Issues

​
Google Drive

Shared Drive Issues Shared drives require special permissions. Make sure:
  • User has access to the shared drive
  • OAuth app has drive.readonly scope
  • User is a member of the shared drive

​
Notion

Database Not Syncing Notion databases need explicit permission. If databases aren’t syncing:
  1. Go to Notion workspace settings
  2. Find your integration under “Connections”
  3. Click on the integration
  4. Select specific pages/databases to share
  5. Re-sync after granting access
Workspace Access For full workspace access, a workspace admin must:
  1. Approve the integration
  2. Grant access to all pages
  3. Enable “Read content” permission

​
OneDrive

Business vs Personal Accounts Business accounts may have additional restrictions:
  • Admin consent might be required
  • Some SharePoint sites may be restricted
  • Compliance policies may block certain files

​
Gmail

Real-time Sync Not Working If emails aren’t syncing in real-time but scheduled/manual sync works:
  1. Real-time sync uses Google Cloud Pub/Sub webhooks
  2. Watch subscriptions expire after 7 days (supermemory auto-renews)
  3. Only INBOX label triggers real-time updates
  4. Trigger a manual sync to verify the connection is healthy:
await client.connections.import('gmail', {
  containerTags: ['user-123']
});
Missing Refresh Token If Gmail stops syncing after initial setup:
  1. The user may have revoked app access in Google Account settings
  2. Delete and recreate the connection
  3. Ensure user completes full OAuth consent flow
// Re-authenticate to get fresh tokens
await client.connections.deleteByProvider('gmail', {
  containerTags: ['user-123']
});

const newConnection = await client.connections.create('gmail', {
  redirectUrl: 'https://yourapp.com/callback',
  containerTags: ['user-123']
});
Scale Plan Required Error Gmail connector requires Scale Plan or Enterprise Plan. If you see access errors:
  • Verify your organization has the required plan
  • Contact support to upgrade your plan

​
Best Practices

  1. Set reasonable document limits - Start with 500-1000 documents
  2. Use descriptive container tags - Makes debugging easier
  3. Monitor failed documents - Check weekly for sync issues
  4. Handle rate limits gracefully - Implement exponential backoff
  5. Test OAuth in development - Ensure redirect URLs work before production
