Unexpected token

It looks like error is not fixed, I got an error while fetching data

Unexpected token < at json at 0```

Let me guess, you were trying to do a POST request and trying to send some data back to the client? This usually happens when you don’t use the body-parser package.

That’s true I am sending post request ,but I used body-parser

How are you initiating body-parser with your app?

app.use(bodyParser.json())
app.use(bodyParser.urlencoded({
extended:true
}))

parse it, worked with mine

Can you show us the bit of code that is giving the error when it cannot parse the json!
