Send Signed Transaction for Contract Interaction on Quorum using web3js - solidity

Question

I am currently running the 7 nodes example given in quorum-examples github repo. I have deployed a very simple storage contract which gets and sets the value. As per the example, I am able to interact with the smart contract inside the geth node cmd line. However I would like to interact with it using another address outside the node and so I wrote the following code:
const Web3 = require('web3')
const web3 = new Web3(new Web3.providers.HttpProvider('http://127.0.0.1:22000'))
const { Transaction } = require('#ethereumjs/tx')
const { default: Common } = require('#ethereumjs/common')
const run = async () => {
const contractInstance = await new web3.eth.Contract(
[
{
constant: true,
inputs: [],
name: 'storedData',
outputs: [{ name: '', type: 'uint256' }],
payable: false,
type: 'function',
},
{
constant: false,
inputs: [{ name: 'x', type: 'uint256' }],
name: 'set',
outputs: [],
payable: false,
type: 'function',
},
{
constant: true,
inputs: [],
name: 'get',
outputs: [{ name: 'retVal', type: 'uint256' }],
payable: false,
type: 'function',
},
{
inputs: [{ name: 'initVal', type: 'uint256' }],
payable: false,
type: 'constructor',
},
],
'0xd9d64b7dc034fafdba5dc2902875a67b5d586420'
)
const customCommon = Common.forCustomChain('mainnet', {
chainId: 10,
})
const txCount = await web3.eth.getTransactionCount(
'ed9d02e382b34818e88b88a309c7fe71e65f419d'
)
const txData = {
nonce: web3.utils.toHex(txCount),
gasLimit: '0x47b760',
gasPrice: '0x00',
value: '0x0',
chainId: 10,
to: '0xd9d64b7dc034fafdba5dc2902875a67b5d586420',
data: contractInstance.methods.set(10).encodeABI(),
}
const tx = Transaction.fromTxData(txData, { common: customCommon })
const signedTx = tx.sign(
Buffer.from(
'e6181caaffff94a09d7e332fc8da9884d99902c7874eb74354bdcadf411929f1',
'hex'
)
)
const serializedTx = signedTx.serialize()
const result = await web3.eth.sendSignedTransaction(
`0x${serializedTx.toString('hex')}`
)
return result
}
run().then(console.log).catch(console.log)
However whenever I try to send the transtion, it always errors out to
"Transaction has been reverted by the EVM:\n{\n \"blockHash\": \"0xd6b06321882912185f5e1d3401a012f58b6bbf7eee1e1d2c6c2cd80a0e13bbdc\",\n \"blockNumber\": 5,\n \"contractAddress\": null,\n \"cumulativeGasUsed\": 23751,\n \"from\": \"0x0fbdc686b912d7722dc86510934589e0aaf3b55a\",\n \"gasUsed\": 23751,\n \"logs\": [],\n \"logsBloom\": \"0x00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000\",\n \"status\": false,\n \"to\": \"0x9d13c6d3afe1721beef56b55d303b09e021e27ab\",\n \"transactionHash\": \"0x8c7fd175ab037e24e531804774e8b89bf5aea25de8d99aa9bc2c034229603299\",\n \"transactionIndex\": 0\n}",
Do let me know if more info is required and I will update the post.
The smartcontract code is as follows:
pragma solidity ^0.5.0;
contract simplestorage {
uint public storedData;
constructor(uint initVal) public {
storedData = initVal;
}
function set(uint x) public {
storedData = x;
}
function get() view public returns (uint retVal) {
return storedData;
}
}

I think i met the similar issue as well. My issue was invalid chain id signer. I checked many docs and tried to set the custom chain id which was what you did about "common". But nothing changed until i changed the version of ethereumjs-tx to ^1.3.7. btw you dont need common if you try my solution.
