TestRPC/Ganache: the tx doesn't have the correct nonce

Question

I have been experimenting with truffle recently and followed the following tutorial: http://truffleframework.com/tutorials/pet-shop

Whenever I try to setup a transaction I keep getting the same error below

Error: Error: the tx doesn't have the correct nonce. account has nonce of: 14 tx has nonce of: 0

Checked online and read up on a lot of articles related to this but so far haven't found what might be causing this issue.

• Truffle v3.4.7
• Solidity v0.4.13
• Npm v5.3.0
• TestRPC v4.0.1 (also happen with Ganache)
• Metamask v3.9.5

From what I understand it seems it is unable to find the previous transactions to hash the new transaction?

Answer 1

Using MetaMask v3.14.1 you can reset your account as follow:

Resetting an Account In the Settings menu, MetaMask has a "Reset Account" button. This button wipes the current account's transaction history, which is used to calculate the current account nonce.

Normal users should never have a reason to use this feature.

This is useful for developers who reset a test network but want to continue using the same account, forcing MetaMask to believe this network ID is a clean network in a fresh state.

Old response: Answer of yatskevich is correct.

However, for people how are using Truffle 4+ with "truffle develop", you need to remove and reinstall MetaMask to get it work again, every time you run Truffle Develop!

This issue is addressed here: https://github.com/trufflesuite/truffle/issues/681, here: https://github.com/trufflesuite/ganache/issues/112, and also here: https://github.com/MetaMask/metamask-extension/issues/1999

In short they are working on it and in the mean time you need to reinstall MetaMask every time!

Answer 2

Try to reconnect to your TestRPC network in MetaMask:

1. Select Main Ethereum Network (or any other than Localhost 8545)
2. Select Localhost 8545 again

I've stumbled upon this issue after stopping and starting a new TestRPC node.

Answer 3

Check your truffle.js or truffle-config.js

if you are using the HDWalletProvider like below, it seems that this is what causing the error

var HDWalletProvider = require("truffle-hdwallet-provider");
var mnemonic = "your mnemonic";

module.exports = {
  networks: {
    development: {
      provider: function() {
        return new HDWalletProvider(mnemonic, "http://127.0.0.1:8545/", 0, 50);
      },
      network_id: '*',
      gas: 9999999
    }
  },
  compilers: {
    solc: {
      version: "^0.4.25"
    }
  }
};

remove the HDWalletProvider like below, it solves mine

module.exports = {
  networks: {
    development: {
      host: "127.0.0.1",     // Localhost
      port: 8545,            // Standard Ganache UI port
      network_id: "*", 
      gas: 4600000
    }
  },
  compilers: {
    solc: {
      version: "0.5.2"
    }
  }
};
