This section contains a list of all possible errors that might occur while using
import { Unirep } from '@unirep/contracts/Unirep.sol';
info
When developing with hardhat environment, these custom errors can be seen in the _selector
:
Error: cannot estimate gas; transaction may fail or may require manual gas limit

0x099cfcff
UserAlreadySignedUp(uint256 identityCommitment)
The given identity commitment has already signed up in the current Unirep contract.
A user cannot double sign-up in an application.
0x6767dda1
AttesterAlreadySignUp(uint160 attester)
The attester has already signed up in the current Unirep contract.
An attester cannot double sign-up in the Unirep protocol.
0xd724105a
AttesterNotSignUp(uint160 attester)
The attester has not signed up in the current Unirep contract.
Please callattesterSignUp()
0xd7aa5847
AttesterInvalid()
The given attester address is not a validuint160
type data.
Please check if the attester address is correctly assigned while generating proofs.
0xa78d09b9
CallerInvalid()
The caller address is not the same as the attester address in a proof verification contract.
Please verify the caller address.
0xdc215c0a
NullifierAlreadyUsed(uint256 nullilier)
The nullifier is already used in Unirep contract.
A nullifier cannot be submitted twice in the Unirep protocol.
0xedc650d7
AttesterIdNotMatch(uint160 attesterId)
Themsg.sender
does not match the claimed attester ID.
Please send the transaction through the attester.
0x7db3aba7
OutOfRange()
A replacement field data cannot be out ofSNARK_SCALAR_FIELD
.
Please use a value which is less thanSNARK_SCALAR_FIELD
.
0x7fa0b337
InvalidField()
An attestation was made to a field that was either out of range, or not capable of receiving attestations.
0xb7d09497
InvalidTimestamp
If a user is signed up by an attester manually, the timestamp field should be0
.
0x8baa579f
InvalidSignature()
The signature does not match the attester ID.
Please make sure the signature is signed through the correct attester.
0x2217bbbc
InvalidEpochKey()
If The epoch key is greater thanSNARK_SCALAR_FIELD
is recognized invalid.
0x53d3ff53
EpochNotMatch()
Current epoch does not match the epoch in the proof or the target epoch.
Please check the current epoch and generate a corresponding proof.
0xa225656d
InvalidEpoch(uint256 epoch)
The epoch in the proof is greater than the current epoch.
Please check the current epoch and generate a corresponding proof.
0x09bde339
InvalidProof()
The proof is verified invalid through on-chain verifiers.
Please verify it with the off-chain prover.
If it is valid off-chain but invalid through on-chain verifiers, please check the if the proving keys match the ones on-chain.
0xf1b8a45e
InvalidStateTreeRoot(uint256 stateTreeRoot)
The state tree root of given epoch does not exist in the current Unirep contract.
There are several reasons:- The user does not sign up successfully
- The user does not perform user state transition successfully
userSignUp
transaction oruserStateTransition
transaction is pending- Epoch and state tree root does not match
0xd542f669
InvalidHistoryTreeRoot(uint256 historyTreeRoot)
The epoch tree root of given epoch does not match the current Unirep contract.
Please check if all attestations are processed correctly and successfully.
