Describe the Problem

I have a transaction object was populated with type 0:

tx = {"to"=>"0x3f1B32386dE69693F708204BEC1568aB6599E0e6",
 "value"=>"0x16345785d8a0000",
 "data"=>"0x",
 "type"=>0,
 "nonce"=>0,
 "gasLimit"=>{"type"=>"BigNumber", "hex"=>"0x5208"},
 "gasPrice"=>{"type"=>"BigNumber", "hex"=>"0x59682f10"},
 "from"=>"0xc9aAD004e656153e7Ea4633BbF3Dc10BcE7a50fb",
 "chainId"=>80001}

When I sign it (offline) with code below:

      const signer = new ethers.Wallet(privateKey);
      const txRaw = await signer.signTransaction(tx);

Then I get error: {"reason"=>"invalid hexlify value", "code"=>"INVALID_ARGUMENT", "argument"=>"value", "value"=>{"type"=>"BigNumber", "hex"=>"0x59682f10"}}

If I populate transaction using type 2:

{"to"=>"0x3f1B32386dE69693F708204BEC1568aB6599E0e6",
 "value"=>"0x16345785d8a0000",
 "data"=>"0x",
 "type"=>2,
 "nonce"=>0,
 "gasLimit"=>{"type"=>"BigNumber", "hex"=>"0x5208"},
 "gasPrice"=>nil,
 "from"=>"0xc9aAD004e656153e7Ea4633BbF3Dc10BcE7a50fb",
 "maxFeePerGas"=>{"type"=>"BigNumber", "hex"=>"0x59682f20"},
 "maxPriorityFeePerGas"=>{"type"=>"BigNumber", "hex"=>"0x59682f00"},
 "chainId"=>80001}

Then it will be signed ok

Plz help, thanks!

I found it, If I change tx from

tx = {"to"=>"0x3f1B32386dE69693F708204BEC1568aB6599E0e6",
 "value"=>"0x16345785d8a0000",
 "data"=>"0x",
 "type"=>0,
 "nonce"=>0,
 "gasLimit"=>{"type"=>"BigNumber", "hex"=>"0x5208"},
 "gasPrice"=>{"type"=>"BigNumber", "hex"=>"0x59682f10"},
 "from"=>"0xc9aAD004e656153e7Ea4633BbF3Dc10BcE7a50fb",
 "chainId"=>80001}

to

tx = {"to"=>"0x3f1B32386dE69693F708204BEC1568aB6599E0e6",
 "value"=>"0x16345785d8a0000",
 "data"=>"0x",
 "type"=>0,
 "nonce"=>0,
 "gasLimit"=>"0x5208",
 "gasPrice"=>"0x59682f10",
 "from"=>"0xc9aAD004e656153e7Ea4633BbF3Dc10BcE7a50fb",
 "chainId"=>80001}

it will work.

Note that I populate the tx with:

    const provider = new ethers.providers.JsonRpcProvider(nodeUrl);
    const signer = provider.getSigner(fromAddress);

    try {
      const tx = await signer.populateTransaction({
        to: toAddress,
        value: amount,
        data: "0x",
        type: 0
      });
