When I try to fetch and pass some variables to ejs,error something like below has occured.

    27|                 <div id="content">
 >> 29|                 <%=json%>
    30|                 </div>
json is not defined

My current work is like below. Are there any problem? If somone has opinion,please let me know. Thanks

const fetch = require("node-fetch");
const express = require("express");
const app = express();

const API_KEY="https://opentdb.com/api.php?amount=1&type=multiple";


app.get('/', (req, res) => {
  fetch(API_KEY)
      .then(response => response.json())
      .then(json => {
       console.log(json);    
       res.render("quiz.ejs", json);
    
      });
});

app.listen(8080,()=>{
    console.log('server is running!');
});

              <div id="content">
                  <%= json %>
                </div>

Here, is how you can do it

app.get('/', (req, res) => {
   fetch(API_KEY)
      .then(response => response.json())
      .then(json => {
         console.log(json);
         res.render("quiz.ejs", {
            json: json
         });
      });
});

so, to print an object to the template (ejs) we first need to stringify it:

<%= JSON.stringify(json)%>

On the rendering section of your code. Try sending second argument inside the curly braces as like

res.render('quiz.ejs', {json});
