Hello HTB Community! I am working through File Upload Module and on the Client-Side validation Chapter when I launch the machine it seems that upload button doesn’t even work at all. While using dev tools and console I found out that whenever I press “Upload” button I get this error:

Uncaught TypeError: file is undefined
    validate http://94.237.48.48:33777/script.js:9
    onsubmit http://94.237.48.48:33777/:1

Is anyone else experiencing this issue with this lab, I tried to restart the machine, but it didn’t help? Thank you in advance!

Forget it, I am stupid. All you have to do is first to click on Avatar Icon, and then upload a file. I am an idiot
