执行truffle.migrate时发生错误，“ undefined”的参数数量无效

Question

I'am trying to deploy a smart contract :

`
pragma solidity >=0.4.21;

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 have created 2_deploy.js

var SimpleStorage = artifacts.require("SimpleStorage");

module.exports = function(deployer) {
// Pass 42 to the contract as the first constructor parameter
deployer.deploy(SimpleStorage, 42, {privateFor: 
["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc="]})
};

but when I execute truffle.migration I obtain this error:

 'Error encountered, bailing. Network state unknown. Review 
 successful transactions manually.
  Error: Invalid number of parameters for "undefined". Got 2 
  expected 1!

Truffle v5.0.13 (core: 5.0.13)
Node v8.9.4''

do anyone knows how to deal with the problem?

Answer 1

Truffle has only recently added support for quorum private transactions. So you need Truffle version 5.0.14. I hope that helps.
