I am trying to make a multisig contract account on zksync. Here is my AAFactory.sol

contract AAFactory {

aaBytecodeHash = _aaBytecodeHash;
}
function deployAccount(
bytes32 _salt,

) external returns (address accountAddress) {
(bool success, bytes memory returnData) = SystemContractsCaller
.systemCallWithReturndata(
uint32(gasleft()),
address(DEPLOYER_SYSTEM_CONTRACT),
uint128(0),
abi.encodeCall(
IContractDeployer.create2Account,

aaBytecodeHash,

);
if (!success) {
revert AAFactory__AccountDeployerFailed();
}
(accountAddress) = abi.decode(returnData, (address));
}
}
aaBytecodeHash is the bytecode of MultisigAA.sol
I deployed the AAFactory successfully.
But when I deploy the multisig , I get an error saying execution reverted (unknown custom error)
Here is my multissig deployment script-
const hre = require("hardhat")
const { Wallet, utils, Provider } = require("zksync-ethers")
const addresses = require("../address.json")
const { Deployer } = require("@matterlabs/hardhat-zksync-deploy")
const AA_FACTORY_ADDRESS = addresses[hre.network.config.chainId]
module.exports = async () => {
const provider = new Provider(hre.userConfig.networks.zkSyncTestnet.url)
const wallet = new Wallet(process.env.RICH_ACCOUNTS_PRIVATE_KEY, provider)
const factoryArtifact = await hre.artifacts.readArtifact("AAFactory")
const aaFactory = new hre.ethers.Contract(
AA_FACTORY_ADDRESS,
factoryArtifact.abi,
wallet
)
const owner1 = Wallet.createRandom()
const owner2 = Wallet.createRandom()
const salt = hre.ethers.ZeroHash;
const tx = await aaFactory.deployAccount(
salt,
owner1.address,
owner2.address,
)
await tx.wait()
const abiCoder = new hre.ethers.AbiCoder()
const multisigAddress = utils.create2Address(
AA_FACTORY_ADDRESS,
await aaFactory.aaBytecodeHash(),
salt,
abiCoder.encode(['address', 'address'], [owner1.address, owner2.address])
)
console.log(`Multisig account deployed on address ${multisigAddress}`)
}
The error comes from the aaFactory.deployAccount function. The error-
Error: execution reverted (unknown custom error) (action="estimateGas", data="0xb0591126", reason=null, transaction={ "data": "0x76fb8b65000000000000000000000000000000000000000000000000000000000000000000000000000000000000000087f2d1d29b19486b0ea15131f1a2be0755f402fc000000000000000000000000dc3c0ddd0c52857dc41b55072c1132f57712a7e5", "from": "0xBC989fDe9e54cAd2aB4392Af6dF60f04873A033A", "to": "0xa85a2DFAe6bead4f408Fcc6EB8a3ec6C7AaCE9Eb" }, invocation=null, revert=null, code=CALL_EXCEPTION, version=6.13.1)

I tried with a override like this-
const salt = hre.ethers.ZeroHash;
const override = {
gasLimit: BigInt("20000000")
}
const tx = await aaFactory.deployAccount(
salt,
owner1.address,
owner2.address,
override
)
await tx.wait()
But I get this error after that-
