Error Python Webserver 3.11.2 by testing Solidity contract - python-3.x

Question

I tried to test some Solidity contracs with Pyton Webserver 3 to interact by web-UI with Metamask. Pyton is working fine, but I only get the project directory not the desired webUI with a button and Pyton sends

I'm not sure, if that's a problem with Pyton itself or if something's missing in index.ts
import { ethers } from "ethers";
function getEth()
{
// #ts-ignore
const eth = window.etherium;
if (!eth)
{
throw new Error("please get Metamask");
}
return eth;
}
async function hasAccounts()
{
const eth = getEth();
const accounts = await eth.request({method: "eth_accounts"}) as string[];
return accounts && accounts.length;
}
async function requestAccounts()
{
const eth = getEth();
const accounts = await eth.request({method: "eth_requestAccounts"}) as string[];
return accounts && accounts.length;
}
async function run()
{
if (!await hasAccounts() && !await requestAccounts())
{
throw new Error("Please let me take your money");
}
const counter = new ethers.Contract
(
process.env.CONTRACT_ADDRESS,
[
"function count() public",
"function function getCounter() public view returns(uint)",
],
new ethers.providers.Web3Provider(getEth()).getSigner()
)
const el = document.createElement("div");
async function setCounter()
{
el.innerHTML = await counter.getCounter();
}
setCounter();
const button = document.createElement("button");
button.innerText = "increment";
button.onclick = async function()
{
await counter.count();
//setCounter();
}
document.body.appendChild(el);
document.body.appendChild(button);
}
run();
index.html and index.ts are in the same directory named /src and if I go into that directory in the localhost-Window it only shows an empty screen, Source code
<html>
<head>
<body></body>
</head>
</html>
Is there a better webserver than Pyton to test contracts on localshost?
starting Python and calling/ refresing localhost:8000

Answer 1

Your web server expects a favicon
Errno 2] No such file or directory: 'C:\\_jpegdegens\\favicon.ico
I would assume adding this file will make your web server to function properly.
Wikipedia has more information what is a favicon and how to create one.
