Tell us what’s happening:
My code is failing every step after step 13. It works initially, but for some reason doesn’t give Status: INSUFFICIENT_FUNDS or Status: CLOSED correctly after running out of money in the drawer when the button is pushed repeatedly. I’m stuck on what to do to make it handle that properly. (Sorry for the multiple different help posts aha, this project is really stumping me. Also sorry for the excessive console logs, I’m really trying to watch every step of the process to catch what’s going wrong but I’m not really getting it.)
Your code so far
