VoidSigner cannot sign transactions

[DeployIsComing]

Hello,
I'm trying to mint an NFT through proxy and I'm always receiving this message

"VoidSigner cannot sign transactions"

I found this error is thrown from VoidSigner class. Does anybody know what it is? How to fix?

Thanks!

That’s the entire purpose of a VoidSigner, to not be able to sign things. It doesn’t have access to a private key, and just responds to .getAddress() with the given address.

I see your point of view, but it doesn't make sense. I'm going to paste below a code snippet and show you where this error message is being thrown.

const provider = new ethers.providers.JsonRpcProvider('.....goerli.......')

const wallet = new ethers.Wallet(config.MetamaskPrivateKey, provider) 

const marketPlaceContract = new ethers.Contract(config.MarketPlaceContract, abiMarketPlace, wallet)

const registryContract = new ethers.Contract(config.RegistryContract, abiRegistry, wallet)

const authenticatedRegistryContract = new ethers.Contract(config.RegistryContract, abiAuthenticatedProxy, wallet)

let buyerProxyAddress = await registryContract.proxies(wallet.address)

// Check if address is 0x0000.... so create a new one
if (!checkEthAddress(buyerProxyAddress)) {
const buyerRegisteredProxy = await registryContract.connect(wallet).registerProxy()
buyerProxyAddress = await registryContract.proxies(wallet.address)
}

const buyerProxy = authenticatedRegistryContract.connect(buyerProxyAddress, wallet)

let voucherObject = JSON.parse(voucherJsonFROM_AXIOS)

const call = marketPlaceContract.interface.encodeFunctionData('executeLazy', [voucherObject])

// Here is throwing the error: "VoidSigner cannot sign transactions"
// I had to add gasPrice and GasLimit because it was asking for it. 
// Now Im receiving VoidSigner and I don't know where is the problem the smart-contract passed in all unit tests. 
const tx = await buyerProxy.proxy(
          marketPlaceContract.address,
          0,
          call,
          { gasPrice: 100, gasLimit: 9000000 }
      )

Hello, just to let you know... I managed to solve this problem. The problem was because I was informing the wallet not signer... so first of all get metamask signer

await window.ethereum.enable()
    const buyerProvider = new ethers.providers.Web3Provider(window.ethereum);
    const signer = buyerProvider.getSigner()

then provide signer to proxy

const buyerProxy = await authenticatedRegistryContract.connect(signer, buyerProxyAddress)

BANNG!!
