Personal library - Replit failed(Hmm couldn't reach) after test

I am working on the personal library project below and passed the own-make functional test. I also passed the test on project page except the last one since my web app cannot restore from the functional test.

Though I finally passed the test by changing the setTimeout test from 1500 to 4500 and submit my URL quickly, I still cannot find why I was failed.

I refer to two links below. One is remove the Rrequire(‘dotenv’).config() and the other one is remove the port environmental variable but these does not work.

My project URL is posted below:

Many Thanks!

I have the same problem. No idea why. Maybe problem in replit.
