AA33 reverted (or OOG)

The paymaster signature was rejected or verifying the paymaster signature ran out of gas.

Possible Solutions

1. Check that the verificationGasLimit is high enough to cover the validatePaymasterUserOp function's gas costs.
2. If you are using a Alchemy's Gas Manager, and the userOp is well formed with a high enough verificationGasLimit, reach out.
3. If you are using another paymaster service, contact them.
