why does gnosis doesn't accept my input argument for the set up?

Question

I'm setting up a safe and when trying to setting it up I'm adding some inputs that look eligible because i checked them with some other codes that were doing the same thing but I get an error on the arguments.

export async function createSafe() {
  const { daoMember1, daoMember2, daoMember3, daoMember4 } = await getAccounts()

  // Deploy Gnosis Safe master copy contract
  const masterCopyFactory = await ethers.getContractFactory('GnosisSafe')
  const masterCopy = await masterCopyFactory.deploy()

  // Deploy Gnosis Safe proxy factory contract
  const proxyFactoryFactory = await ethers.getContractFactory('GnosisSafeProxyFactory')
  const proxyFactory = await proxyFactoryFactory.deploy()

  // Create Gnosis Safe contract

  const safeProxy = await proxyFactory.createProxy(masterCopy.address, '0x')
  const safe = await ethers.getContractAt('GnosisSafe', masterCopy.address)

  // Set up Gnosis Safe contract with owners and threshold
  await safe.setup(
    [daoMember1.address],
    1,
    ethers.constants.AddressZero,
    '0x',
    ethers.constants.AddressZero,
    ethers.constants.AddressZero,
    0,
    ethers.constants.AddressZero
  )

  return safe

}

There's a problem with the owner addition process in the Gnosis Safe contract, you only have one owner (daoMember1.address) and a threshold of 1. Just replace this part of your code

edit: lets try to get the Safe address from the transaction receipt

export async function createSafe() {
  const { daoMember1, daoMember2, daoMember3, daoMember4 } = await getAccounts()

  const masterCopyFactory = await ethers.getContractFactory('GnosisSafe')
  const masterCopy = await masterCopyFactory.deploy()

  const proxyFactoryFactory = await ethers.getContractFactory('GnosisSafeProxyFactory')
  const proxyFactory = await proxyFactoryFactory.deploy()

  const safeProxy = await proxyFactory.createProxy(masterCopy.address, '0x')

  const safeAddress = safeProxy.events[0].args.proxy
  const safe = await ethers.getContractAt('GnosisSafe', safeAddress)

  await safe.setup(
    [daoMember1.address],
    1,
    ethers.constants.AddressZero,
    '0x',
    ethers.constants.AddressZero,
    ethers.constants.AddressZero,
    0,
    ethers.constants.AddressZero
  )

  return safe
}
