When I use the Reader.read() (referenced in the main file as read()) command, it apparently does nothing, because the next command tries to convert it to a string (it originally was a tuple) and it just dumps a NoneType error, it worked yesterday(August 25th 2021)... Any clues?
Have you tried the debugger in the replete ide? It's super easy to use, should show the state of your variables I'm pretty sure, and is right there in the sidebar. Just set a couple breakpoints or step through the code. You'll probably find the problem pretty fast.
