I had the same error!
Express v14.17.3

I edit this lines in server.js:
// parse requests of content-type - application/json
app.use(express.json());
// parse requests of content-type - application/x-www-form-urlencoded
app.use(express.urlencoded({ extended: true }));

And I realised that Postman is not sending the POST request as expected, I used advancedrestclient instead with no problems.

Make sure to delete bodyParser below.
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

Replace it with the new native express integration.
app.use(express.json());
app.use(express.urlencoded({extended: true}));

When you send the request to the API, use JSON format. I recommend to use "Insomnia" to test.

No that didn't worked. Still getting the same error.
