Social Recovery Module (Develop) - Logic Error

[4NNNN]

function _init(bytes calldata data) internal override {
(address[] memory _guardians, uint256 _threshold, bytes32 _guardianHash) =
abi.decode(data, (address[], uint256, bytes32));
address _sender = sender();
require(_threshold > 0 && _threshold <= _guardians.length, "threshold error");
if (_guardians.length > 0) {
require(_guardianHash == bytes32(0), "cannot set anonomous guardian with onchain guardian");
}
if (_guardians.length == 0) {
require(_guardianHash != bytes32(0), "guardian config error");
}
for (uint256 i = 0; i < _guardians.length; i++) {
walletGuardian[_sender].guardians.add(_guardians[i]);
}
walletGuardian[_sender].guardianHash = _guardianHash;
walletGuardian[_sender].threshold = _threshold;
walletInitSeed[_sender] = _newSeed();
}

There's a threshold error when, implementing the anon flow for setting up the anon guardian recovery module. Well seems like it's a logic error where if the inputs for the guardian hash are provided with threshold and owners being zero. Either way the threshold has to be greater than 0, well neglecting the flow of anon guardianhash recovery !
