Subject: [PATCH] Updated

There was a problem that i faced .I was not able to see data(full name,email,mobile,city)in" view all" field .But still data was present in my database in mongoDB compass.
I found that i should install package by command "npm install @handlebars/allow-prototype-access" and should add above modification i.e
1.const Handlebars = require('handlebars')
2.const {allowInsecurePrototypeAccess} = require('@handlebars/allow-prototype-access')
and instead
3.app.engine('hbs', exphbs({ extname: 'hbs', defaultLayout: 'mainLayout', layoutsDir: __dirname + '/views/layouts/' }));
use:
4.app.engine('hbs', exphbs({ extname: 'hbs', handlebars: allowInsecurePrototypeAccess(Handlebars), defaultLayout: 'mainlayout', layoutsDir: __dirname + '/views/layouts/' }));
     will solve the problem and data can be seen in require field on browser...local host whatever u are using
