# Error AA14: InitCode Must Return Sender

The smart account address deployed via `initCode` doesn't match the `sender` address in the user operation.

## Potential Fixes

1. Ensure `initCode` accuracy
2. Verify that the `sender` address is deterministically generated from `initCode` (consider using [getSenderAddress](/permissionless/reference/public-actions/getSenderAddress))
3. Check the factory address in `initCode` (first 20 bytes).
4. If issues persist, investigate `initCode` deployment using [Tenderly](https://tenderly.co/)

By ensuring the correct generation and matching of addresses, you can resolve the AA14 error.
