I am getting a 401 error every time I click the delete button. I downloaded the source code provided by mosh at the start of the section but still getting the same error.  
Someone, Please help.

Ensure that the current user is an admin. You can manually add in the mongodb. The backend (Node.js) allows only the admin to modify the data. Such as creating, deleting and so on. Exception with status code 401 means unauthorized access.

I couldn’t get it from GitHub. I just used the provided folder at the beginning of the section.  
At first I got some errors. And then I ran the following commands:  
npm install node-gyp -g  
npm install bcrypt -g  
npm install bcrypt --save  
This worked for me
