How to correct a 404 error when I fetch Data from DataBase?

Question

I want to fetch data from SQL server using Redis-Caching , but when I send the request (GET http://localhost:4000/product/Data) => I see this error:

GET /product/Data 404 7.390 ms - 33
GET /product/Data - - ms - -
, How can I solve it ?

server.js :

const redis = require("redis");
const redisUrl='redis://127.0.0.1:6379';
// create Redis client on Redis port
const client = redis.createClient(redisUrl);
// create express application instance

const Data=async(req,res,next)=>{
cache,getData
}
//Make request to DataBase for Data
async function getData(req,res,next){
try{
console.log('Fetching Data From SQL server...')
const Pull_Products=await
SingletonSqlHandler.instance.sendQuery('SELECT * from
dbo.getAllProducts()')
// return Pull_Products;
return res.status(200).send.json(Pull_Products)
}
catch(error){
console.error(error);
res.status(500).json({error:error})
}
}
// Cache midleware
async function cache(req,res,next){
console.log('Fetching Data From Cache...')
const Pull_Products=await
SingletonSqlHandler.instance.sendQuery('SELECT * from
dbo.getAllProducts()')
client.get(Pull_Products,(error,cachedData)=>{
if(error) throw error
if(cachedData!=null){
res.send(setResponse(Pull_Products,cachedData));
}
else {
next();
}
})
}
module.exports={
Data:Data
}
productRoute.js:

const router = require('express').Router();
const Redis=require('../redis-cache/server')
router.get('/Data', Redis.Data);
module.exports = router;
