adding data to database not working

When I click the SignUp button the server just keeps on loading and gives no response. I'm stuck. Please help. Also in the end says : "localhost did not send any data ERR_EMPTY_RESPONSE".

Adding products in database causing issue.

When I add a new document to the Products collection, it causes this problem in execution

I found that's about the chunkSize variable in the shopping/routes/index.js file, that variable must contain exactly the number of products saved in the database, so to keep my app executable, I must manually change the value of chunkSize and every single n equal to that variable (also equal to number of documents in Products collection) after insertion of new product(s), or I can count the number of the docs in that collection with a mongoDB count methods, but this issue is also related to pagination which is not covered in the tutorial, so basically, if I solved the issue of the execution error, I will have another problem, for example if I have 1000 products in the database, they will be shown in a single page, which is inconvenient.

Final Shopping Cart

Do you have a link to the final shopping cart?
