BIIIIG problem: The last 5%.

Did ChatGPT just hallucinate it? Does it exist but it isn't used like ChatGPT says? Does it exist but it doesn't do what ChatGPT thinks it does?

I use ChatGPT sometimes to help out with stuff at home (I've tried it for work stuff but the stuff I work on is niche enough that it purely hallucinates), and I've ended up running in circles for hours because the answer I got ended up in this uncanny valley: Correct enough that it isn't immediately obviously wrong, but incorrect enough that it won't work, it can't work, and you're going to really have to put a lot of work in to figure that out.
