We need to see your GitHub repo or your link for your project.

Thanks for your reply. I just started backend basic node and express. After i npm installed, i npm start but the page shows a 404 error

That is normal and expected.

When I forked your project and clicked the Run button, the npm install and npm start ran automatically with no errors. I suggest deleting that project and re-click the boilerplate link for this section and see what happens.

Hi Randell, thanks for your response. I deleted all my old repos and restart a new boilerplate but got the same error message. I even clone and forked on my local machine and used vscode to install npm packages and npm start… the same result. I’ve attached the error message screen shot below.

I tried on different computer… the same result… do you happen to know what cause the problem?

Oh i just realized what you meant by normal and expected. please ignore my previous messages. no problems at this point. Thank you so much!
