"APIRequest.sendRequest()" doesn't work with erc1155ABI

What happened?

This is when I tried to send tokens using ERC1155.

I generated the signed transaction using the ERC1155ABI. This is a decoded version of that transaction using https://flightwallet.github.io/decode-eth-tx/.

{
  "nonce": 0,
  "gasPrice": 124135355866,
  "gasLimit": 82646,
  "to": "0x29533991~",
  "value": 0,
  "data": "f242432a0000000000000000000000002953399124f0cbb46d2cbacd8a89cf0599974963000000000000000000000000713956a23~~~~~~a0000000000000000000000000000000000000000000000000000000000000000a00000000000000000000000000000000000000000000000000000000000000a00000000000000000000000000000000000000000000000000000000000000000",
  "from": "0xe86cf02b510a238046479~",
  "r": "~",
  "v": "~",
  "s": "~"
}

And this is a decoded version of the “data” using https://lab.miguelmota.com/ethereum-input-data-decoder/example/

{
  "method": "safeTransferFrom",
  "types": [
    "address",
    "address",
    "uint256",
    "uint256",
    "bytes"
  ],
  "inputs": [
    "~~",
    "~",
    {
      "type": "BigNumber",
      "hex": "0x193d~~"

    },
    {
      "type": "BigNumber",
      "hex": "0x0a"
    },
    "0x"
  ],
  "names": [
    "from",
    "to",
    "id",
    "amount",
    "data"
  ]
}

At first glance, there seems to be no mistake. However, when I use “APIRequest.sendRequest()” for this transaction, I get an error

let request: APIRequest = .sendRawTransaction(tx)
let response: APIResponse<Hash> = try await APIRequest.sendRequest(with: web3.provider, for: request)

The error message is here.

Swift.DecodingError.keyNotFound(CodingKeys(stringValue: "result", intValue: nil), Swift.DecodingError.Context(codingPath: [], debugDescription: "No value associated with key CodingKeys(stringValue: \"result\", intValue: nil) (\"result\").", underlyingError: nil))

What are the steps to reproduce?

Step1 : Please create a transaction first.

contract.createWriteOperation("safeTransferFrom", parameters: [originalOwner, to, id, value, data] as [AnyObject] )

Step2：Please sign the transaction

Web3Signer.signTX(transaction: &writeOp.transaction,
                                  keystore: web3.provider.attachedKeystoreManager!,
                                  account: self.address! ,
                                  password: "")

Step3 Write that transaction into the chain.

let request: APIRequest = .sendRawTransaction(tx)
let response: APIResponse<Hash> = try await APIRequest.sendRequest(with: web3.provider, for: request)

What is the expected behavior?

If the transfer is successful, a hash of the transaction should be returned.

What is the error thrown?

Swift.DecodingError.keyNotFound(CodingKeys(stringValue: “result”, intValue: nil), Swift.DecodingError.Context(codingPath: [], debugDescription: “No value associated with key CodingKeys(stringValue: "result", intValue: nil) ("result").”, underlyingError: nil))

What’s the stack trace said?

@zuv55 unfortunately ERC specs are not the best part of me, so I really don’t know.

Got you, but please fill new issue for that to avoid messing up with different topics within one issue.
