deposit error

[jpitpol]

Following the Readme file, i have deployed the zsc contract and initialised web3 First, in truffle i migrate and then in node i insert the following commands:

__dirname = '[full path to project folder]/anonymous-zether/packages/protocol';
const Client = require(path.join(__dirname, '../anonymous.js/src/client.js'));
Web3 = require('web3');
web3 = new Web3('http://localhost:9545');
contract = require("@truffle/contract");
path = require('path');
deployedJSON  = require(path.join(__dirname, 'build/contracts/ZSC.json'));
var provider = new Web3.providers.WebsocketProvider("ws://localhost:9545");
var deployed = contract(deployedJSON);
deployed.setProvider(provider);
deployed.deployed();
web3.eth.getAccounts().then(function(result) { accounts = result;});
var home;
web3.eth.getAccounts().then((accounts) => { home = accounts[accounts.length - 1];});
deployed.at(deployed.address).then(function(result) {dbg = result});
var alice = new Client(web3,dbg.contract,home)

After these, i follow the command of client.deposit() with the following error:

> alice.deposit(100)
Initiating deposit.
Promise { <pending> }
>

i think the error message is obvious here. you don't have enough ERC20 funds to cover the deposit you are trying to make. you need to mint yourself some funds.

[jpitpol]

on the read.me file you dont specify minting. How do i should mint in node?

[jpitpol]

These commands fixed the issue

cash.mint(home, 150, {from: home}).then(console.log)
cash.approve(dbg.address, 150, {from: home}).then(console.log)
cash.balanceOf.call(home).then(function(result) {balance = result});
assert.equal(balance, 150, "Minting failed");

im publishing them for future problems by other non-professionals
