Replaying Blob Transactions

[vpahari]

Hi there,

I am trying to replay a blob transaction on a forked chain, and I get an error saying "InvalidArgumentsError: unexpected string". I think this is because the hardhat network is not allowing a blob transaction, because if I send a transaction that is not a blob transaction, then it works. I read that the cancun hardfork is the default on the hardhat network, so I am not sure what else the problem could be.

Here is my current code for it.

const hre = require("hardhat");
const helpers = require("@nomicfoundation/hardhat-toolbox/network-helpers");

async function main() {
	var blockNumber = 21322632;

    await network.provider.request({
          method: "hardhat_reset",
          params: [
            {
              forking: {
                jsonRpcUrl: "http://ethereum-archive:8545",
                blockNumber: blockNumber - 1,
              },
              mining: {
                  mempool: {
                      order: "fifo"
                      }
                  }		
            },
          ],
        });

    var blockNumber = await network.provider.send("eth_blockNumber", []);
    console.log(parseInt(blockNumber,16));

    await network.provider.send("evm_setAutomine", [false]);

    // corresponds to transaction hash 0x8497bc598cad731c3c8d1adc5487a24fe54288e3dbd6082032b2221d801c347e
    var currRawTx = "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";

    var sentTxs = await network.provider.send("eth_sendRawTransaction", [currRawTx]);

    var blockSent = await network.provider.send("evm_mine", []);

}

// We recommend this pattern to be able to use async/await everywhere
// and properly handle errors.
main().catch((error) => {
  console.error(error);
  process.exitCode = 1;
});

Here is the error that I receive

InvalidArgumentsError: unexpected string

I can reproduce the error; we need to investigate further.
