AA32 expired or not due
The paymaster's signature used in the paymasterAndData
field of the user operation is not valid, because it is outside of the time range it specified.
The paymaster's validatePaymasterUserOp
function returns validationData
, a bytes32
field. This field is a concatenation of the validAfter
, validUntil
, and aggregator
fields.
This error occurs when the block.timestamp
falls after the validUntil
timestamp, or before the validAfter
timestamp.
Possible solutions
- If you are using Pimlico's paymaster, send the user operation within 10 minutes or extend the validity period up to 24 hours.
- If you are using your own paymaster contract and using time-based signatures, verify that the
validAfter
andvalidUntil
fields are set correctly and that the user operation is sent within the specified range. - If you are using your own paymaster contract and not looking to use time-based signatures, verify that the
validAfter
andvalidUntil
fields are set to0
