Miniterminal not working on Raspberry pi 4

Operating system: Ubuntu 22
Rustc 1.66

Working on tutorial 5 and I cannot get the miniterminal to print anything. I connect my usb to serial cable and the mini terminal prints that serial is connected, but then when I power on the raspberry pi 4 nothing else is printed.

It would seem that my serial cable's documentation is a little misleading or it was assembled incorrectly. Swapping the rx and tx wires solved this.
