how to sign with raw transaction data - EthersJs, Infura

Question

As the below picture display.

If I know the raw transaction data, then how can I sign this transaction with the ethers.js?

Thanks.

Supplement

The raw transaction data is display on the metamask.

I use a dapp.

And in the app, every time widthdraw, it will return the raw data, and need I to confirm with the metamask, So I want to confirm the transaction with ethers.js.

Try

I had tried as these codes:

const ALCHEMY_GOERLI_URL = 'https://mainnet.infura.io/v3/xxxxxx';
    const provider = new ethers.providers.JsonRpcProvider(ALCHEMY_GOERLI_URL);
    let wallet = new ethers.Wallet(params[1]);
    let walletiWithProvider = wallet.connect(provider)
    const nonce = await walletiWithProvider.getTransactionCount(params[0])
    let transaction = {
      to: params[0],
      gasLimit: '300000',
      maxPriorityFeePerGas: ethers.utils.parseUnits('5', 'gwei'),
      maxFeePerGas: ethers.utils.parseUnits('20', 'gwei'),
      nonce: nonce,
      chainId: 1,
      data: targets.payload,
      value: ethers.utils.parseEther(String(formInline.amount))
    };
    
    let tx = await walletiWithProvider.sendTransaction(transaction)
    await tx.wait()
    console.log(tx)
    console.log(tx.hash)
    console.log(tx.nonce)

But this return a error:

processing response error (body="{\"jsonrpc\":\"2.0\",\"id\":44,\"error\":{\"code\":-32602,\"message\":\"invalid argument 1: hex number \\u003e 64 bits\"}}", error={"code":-32602}, requestBody="{\"method\":\"eth_getTransactionCount\",\"params\":...)

I think this maybe the data is error.

Thanks.

Again Supplement

I want to withdraw the ERC20 token (not eth), and as the below codes, I just send eth to myself account.

Thanks for your help.

Infura RPC

     const network = process.env.ETHEREUM_NETWORK; // "goreli"

     const provider = new ethers.providers.InfuraProvider(
                           network,
                           process.env.INFURA_API_KEY // infura api key
                      );
     const signer = new ethers.Wallet(process.env.SIGNER_PRIVATE_KEY, provider); // wallet private key

     const tx = await signer.sendTransaction({
        to: params[0],
        value: ethers.utils.parseEther(String(formInline.amount)),
        data: targets.payload
      });

     await tx.wait();

References : referring to the Infura docs here, seems like what you need is the above extract. Create eip1559_tx.js

I was able to successfully do a 0 ether Transfer with a message using the above code
