Sending transaction is not working

When I try to send a transaction, it throws an error.

This is how I’m trying to sign and send it.

 func signTransaction() {
        let web3 = Web3.InfuraMainnetWeb3()
        let value: String = amountTextField.text ?? "0.0"
        guard let myAddressString = arrayOfAddresses.first else { return }
        let walletAddress = EthereumAddress(myAddressString)! // Your wallet address
        let toAddress = EthereumAddress(addressTextField.text!)!
        let contract = web3.contract(Web3.Utils.coldWalletABI, at: toAddress, abiVersion: 2)!
        let amount = Web3.Utils.parseToBigUInt(value, units: .eth)
        var options = TransactionOptions.defaultOptions
        options.value = amount
        options.from = walletAddress
        options.gasPrice = .automatic
        options.gasLimit = .automatic
        
        let tx = contract.write(
            "fallback",
            parameters: [AnyObject](),
            extraData: Data(),
            transactionOptions: options)!
        print(tx.transaction)
        print(tx.contract)
        do {
            try tx.send()
            print("Successfuly Sent Transaction")
        } catch {
            print(error)
            print("Failed to Send Transaction")
        }
        self.dismiss(animated: true)
    }

And It prints:

typeMismatch(Swift.Array<Any>, Swift.DecodingError.Context(codingPath: [], debugDescription: “Expected to decode Array<Any> but found a dictionary instead.”, underlyingError: nil))

What’s wrong?

Alright, what was the final fix for me was calling tx.send() with password.

So:

try tx.send(password: "yourPassword", transactionOptions: options)

I added KeystoreManager to Web3, but stil is not working.

let web3 = Web3.InfuraMainnetWeb3()
var keystoreManager: KeystoreManager!

func setupWallet() {
        let keychainMnemonicsString = KeychainWrapper.standard.string(forKey: "walletMnemonics")
        let keychainWalletName = KeychainWrapper.standard.string(forKey: "walletName")
        let keychainWalletPassword = KeychainWrapper.standard.string(forKey: "spendingPassword")
        guard let mnemonics = keychainMnemonicsString else { return }
        guard let name = keychainWalletName else { return }
        guard let password = keychainWalletPassword else { return }
        
        let keystore = try! BIP32Keystore(
            mnemonics: mnemonics,
            password: password,
            mnemonicsPassword: "",
            language: .english)!
        
        let keyData = try! JSONEncoder().encode(keystore.keystoreParams)
        let address = keystore.addresses!.first!.address
        let wallet = Web3Wallet(address: address, data: keyData, name: name, isHD: true)
        
        let data = wallet.data
        
        let keystoreDataBIP32 = BIP32Keystore(data)!
        keystoreManager = KeystoreManager([keystoreDataBIP32])
        
        web3.addKeystoreManager(keystoreManager)
    }

Then I called the signTransaction() function as mentioned above.

But now the error is:

inputError(desc: “Failed to locally sign a transaction”)
