松露智能合约错误：参数数量无效

Question

I followed the tutorial of quorum with truffle: https://truffleframework.com/tutorials/building-dapps-for-quorum-private-enterprise-blockchains

Now I want to migrate the SimpleStorage.sol Smart Contract to the blockchain, but I want to make it to add the "PrivateFor" parameter.

This is my Smart Contract:

pragma solidity ^0.4.17;

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;
  }
}

This is my: 2_deploy_simplestorage.js

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

module.exports = function(deployer) {
  deployer.deploy(SimpleStorage, 42, {privateFor: ["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc="]})
};

But when I do truffle migrate, I get this error:

$ truffle migrate

If you're using an HDWalletProvider, it must be Web3 1.0 enabled or your migration will hang.

When I don't add the "privateFor" parameter, it works:

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

module.exports = function(deployer) {
  deployer.deploy(SimpleStorage, 42)
};

But I need this privateFor parameter..

Does someone know how to fix this?

Answer 1

Hey @BlockChainProgrammer. Thanks for guiding me on how to use the Quorum proxy. It worked.

For this error, Try to upgrade/downgrade your truffle version to v4.1.

$ npm install -g truffle@4.1.10

and change the version of solidity to 0.4.24 in your truffle-config.js and the SimpleStorage.sol and add back privateFor in your migration file.

Answer 2

Problem solved!

What I had to do is to downgrade truffle to "4.1.10" with:

truffle uninstall -g

and then

npm install -g truffle@4.1.10

Many thanks to @TS28

Answer 3

In this case of quorum, the

 {
   privateFor: ["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc="]})
 };

was not defined in the contract, and at such the error, but that particular truffle compiler is compatible with Quorum features.

But For non-Quorum users like myself The error Usually means, define a variable in your contract and not a compiler problem. Most likely a parameter not set in the constructor.
