Troubleshooting

Common Issues

API Key Rate Limiting: If you’re seeing rate limit errors, check your key’s usage patterns and consider increasing limits.
Strategy Rejection: If transactions are being rejected, verify that your strategy parameters match your application’s needs.
Insufficient Funds: Ensure your sponsorship account is adequately funded for Type 0 strategies.
User Payment Failure: For Type 1/2 strategies, ensure users have sufficient token balances and have approved the paymaster contract.

Check API Key Status: Verify the API key is active and has enough requests remaining
Verify Network Settings: Confirm you’re using the correct network endpoints (testnet vs mainnet)
Inspect Transaction Logs: UserOperations failures often have detailed error codes that help diagnose issues
Monitor Dashboard: The AA Platform dashboard provides usage statistics and error information
