Strange behavior on polygon with send, send erc20, and contract calls

[mb812]

I'm trying to send a transaction on polygon mumbai. Im using web3swift version 2.6.5. The transaction is sent correctly as I see in the Alchemy logs panel. But the transaction never become available in polyscan mumbai. The same behavior happen with send MATIC, send ERC-20 and contracts.

For example, this is the implementation for send MATIC:

let password = "PASSWORD"
let mnemonic = "12_WORDS_PHRASE"
let keystore = try! BIP32Keystore(mnemonics: mnemonic, password: password)!
let keystoreAddress = EthereumAddress(keystore.addresses!.first!.address)!
let keystoreManager = KeystoreManager([keystore])

let endpoint = "https://polygon-mumbai.g.alchemy.com/v2/API_KEY"
let chainID = BigUInt(80001)
let mumbai = web3(provider: Web3HttpProvider(URL(string: endpoint)!, network: Networks.Custom(networkID: chainID))!)
mumbai.addKeystoreManager(keystoreManager)
        
let toAddress = EthereumAddress("DESTINATION_WALLET")!
let contract = mumbai.contract(Web3.Utils.coldWalletABI, at: toAddress, abiVersion: 2)!
var options = TransactionOptions.defaultOptions
options.value = Web3.Utils.parseToBigUInt("0.01", units: .eth)
options.from = keystoreAddress
options.gasPrice = .automatic
options.gasLimit = .automatic
//options.type = .eip1559
//options.maxFeePerGas = .automatic
//options.maxPriorityFeePerGas = .automatic

let tx = contract.write(
    "fallback",
    parameters: [AnyObject](),
    extraData: Data(),
    transactionOptions: options)!

let result = try! tx.send(password: password)

This is the result from tx.send():

Alchemy log:

Decode transaction:

Polyscan, the tx hash get unreachable after a while. 0x29f9b10318f48d7956076b9f0572cf29bc70cb8681f839bc0b8a85984bb63ad8

The same send ETH transaction from above in goerli work, I can find the txn hash in etherscan goerli.

let endpoint = "https://eth-goerli.g.alchemy.com/v2/API_KEY"
let chainID = BigUInt(5)
let goerli = web3(provider: Web3HttpProvider(URL(string: endpoint)!, network: Networks.Custom(networkID: chainID))!)
goerli.addKeystoreManager(keystoreManager)

What am I doing wrong? Or is it polygon Mumbai not supported by web3swift?

Did you find reason? I have same problem

@mb812 @bbtyou did you tried it on 3.0.3? I'm sorry to say, but 2.* version are deprecated.
