I created a simple web application that fetches data from an API but when I get a response and render the result to ejs file it seems the route is called multiple times

Here are my codes:-

index.js file

import express from "express";
import bodyParser from "body-parser";
import axios from "axios";

const app = express();
const port = 3000;

app.get("/", async (req, res) => {
  console.log("Received a GET request to /");
  try {
    const response = await axios.get("https://api.restful-api.dev/objects");
    const result = response.data;
    console.log(
      "Fetched data from API:",
      result[Math.floor(Math.random() * result.length)]
    );
    res.render("index.ejs", {
      data: result[Math.floor(Math.random() * result.length)],
    });
  } catch (error) {
    console.error("Failed to make request:", error.message);
  }
});
app.listen(port, () => {
  console.log(`Server running on port: ${port}`);
});

index.ejs file looks like this:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>API - TEST</title>
  </head>
  <body>
    <h1>Welcome to API TEST</h1>
    <h2>Device Name = <%= data.name %></h2>
    <% console.log("Home Page rendered successfully", data.id) %>
  </body>
</html>

And here are my results in the console when I run the web

I need help knowing what is happening so that it can run more than once.

I tied running this code (both using nodemon and simply with node index.js) and when loading http://localhost:3000 in browser (or using curl) I get only one "Home Page rendered successfully" message.

Are you sure that this code is enough to reproduce your problem? How exactly do you make the request to your server?

I got the solution, I found the problem was the extension (Torrent Scanner) in my browser, it refreshed the page and caused the duplication of output objects shown in the console...
