inbox error: i: VM Exception while processing transaction: invalid opcode about ethereum-solidity-course-updated-code HOT 3 CLOSED

Hi @kurtappelmans, sorry for the late response. I assume you mean setMessage().send() instead of setMessage().call(). Could you share the full contents of your Inbox.test.js test file?

Dear, thank you for your reply. I'm basically using your code:

const assert = require("assert");
const ganache = require("ganache-cli");
const Web3 = require("web3");
const provider = ganache.provider();
const web3 = new Web3(provider);
const { abi, evm } = require("../compile");

const message = "Hi there!";
let accounts;
let inbox;

beforeEach(async () => {
// Get a list of all accounts.
accounts = await web3.eth.getAccounts();

// Use one of those accounts to deploy the contract.
inbox = await new web3.eth.Contract(abi)
.deploy({ data: "0x" + evm.bytecode.object, arguments: [message] })
.send({ from: accounts[0], gas: "900000" });
});

describe("Inbox", () => {
it("deploys a contract", () => {
assert.ok(inbox.options.address);
});

it("has a default message", async () => {
const msg = await inbox.methods.message().call();
assert.strictEqual(msg, message);
});

it("can change the message", async () => {
const newMsg = "bye";
await inbox.methods.setMessage(newMsg).send({ from: accounts[0] });

const msg = await inbox.methods.message().call();
assert.strictEqual(msg, newMsg);

});
});

For some reason it works now. Thank you very much for your help!
