I had a similar experience. I asked it about an obscure software engineering question (I think it was about whether there were any software libraries for mapping objects in a Datalog database to a JSON representation of that data). It recommended I use several non-existent technologies, and when I asked it where the documentation for these technologies were, it apologized and told me something to the effect of "this technology that I just made up to answer your question is what the technology would be called if it exsited." Because that is how it works, it just guesses the next word in the sentence based on advanced statistical models of language. It is not sophisticated enough to model the real world and run symbolic logic computations on those models. This will happen in due time, but ChatGPT cannot do it yet.
ChatGPT has no Internet connection so it cannot confirm facts using a search engine. It has "memorized" the entire internet, but if you ask question about a not-well-known computer language, or a very new computer language, it will just make shit up.
