I want to pay a transaction fee with a kda and it fails. The transaction with KLV works without any problems.

let selectedkdaFee = "KONG-3UEQ";

const txOptions = selectedkdaFee ? { kdaFee: selectedkdaFee } : undefined;

const unsignedTx = await kleverInstance.buildTransaction(
      [{
        payload: {
          address: CONTRACT_ADDRESS,
          scType: 0,
          ...payload
        },
        type: Types.TransactionType.SmartContract
      }],
      [encodedData],
      txOptions,
      200000000
    );

The transaction is created, signed and fails during the broadcast.

broadcastResult: {
  "data": null,
  "error": "validation error: invalid transaction 0: invalid signature",
  "code": "bad_request"
}

unsigned tx:

unsignedTx: {
  "RawData": {
    "Nonce": 1250,
    "Sender": "YXePx2qiybMKCl8iISw+JTGURIQolI/KjiWI7s001VM=",
    "Contract": [

        }
      }
    ],

    ],

    "KDAFee": {
      "KDA": "S09ORy0zVUVR",
      "Amount": 3953
    }
  },
  "GasLimit": 100000000
}

@CryptoJaeger are you using the klever extension to broadcast this transaction?

We noticed a bug on the Klever Extension on this situation. We’ve just upload a new version to Chrome Store. Please, update your extension to version 2.19.33 and let us know if the issue was fixed.
