express and moralis token price API not fetching json data in console

I've been following video link from Moralis web3 (youtube) meanwgile I got stuck when I need to fetch data using token price Moralis API. I want the price details to be printed in the console when i do

npm start

the expected output in console is:

{
  nativePrice: {
    value: '13851123944545175839',
    decimals: 18,
    name: 'Ether',
    symbol: 'ETH'
  },
  usdPrice: 23176.58785953117,
  exchangeAddress: '0x1f98431c8ad98523631ae4a59f267346ea31f984',
  exchangeName: 'Uniswap v3'
}

In localhost it should return empty json object '{}' but when I opened the same in localhost it is showing:

Cannot GET /tokenPrice

I tried different method provided in moralis doc its working fine but I did same as the tutorial that throws me error:

const express = require("express");
const Moralis = require("moralis").default;
const { EvmChain } = require("@moralisweb3/common-evm-utils");
const app = express();
const cors = require("cors");
require("dotenv").config();
const port = 3001;

app.use(cors());
app.use(express.json());

app.get("./tokenPrice", async (req, res) => {
  const { query } = req;

  const responseOne = await Moralis.EvmApi.token.getTokenPrice({
    address: query.addressOne,
  });

  const responseTwo = await Moralis.EvmApi.token.getTokenPrice({
    address: query.addressTwo,
  });

  console.log(responseOne.raw);
  console.log(responseTwo.raw);

  return res.status(200).json({});
});

Moralis.start({
  apiKey: process.env.MORALIS_KEY,
}).then(() => {
  app.listen(port, () => {
    console.log(`Listening for API Calls`);
  });
});

also I want to know what does that {query} & addressOne means here as I've never declared any var like before in my code.

• I want to know what {query} and addressOne is , whether express js property or moralis
• want to know why and where error occured and solution to resolve.

For addressOne and addressTwo, those are the query parameters used in your request. If you check the video you can see him showcasing an example of how the request should look like:

http://localhost:3001/tokenPrice?addressOne=0x51491...cf986ca&addressTwo=0xdac17f...6994597

And use 2 addresses of the tokens you wish to get the price for. You can indeed extend the logic to use more addresses

In the video at minute 45:00 You can see how the code should look like. Please make sure you complete your code for it to work properly.
