I just saw a code from 5 years ago .. WTH I was doing ?!!

Today I had to restart a VM that should contain only an apache server, after a period of time some clients complained that there a functionality in the system is not working. I checked the code and I found that this functionality is depends on local server in deferent port, so I back to VM log and found there was a node server was working on this port.
Every thing was fine till now, I check folders but there is no FUCKIN js files for node server.
After hours of searching I found 5 files in the public/assets/dist/js path that named with the same functionality name and a number 1 to 4 and the 5th one is a TEST.js. After checking all files I discovered that the server file is the TEST.js !!!!! seriously WTF ...

When you at work and the internet is down ☻.
