No, because I don't know what line 124 is or what the problem is.

Do you really think we want to start counting lines to find out which of nearly 300 lines is the one it's complaining about, and then try to work out from context what that line was meant to do and what - and when - it might "have a problem"?

You need to start learning how to ask questions: remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with.

So the first thing you will have to do is to learn how to ask a question, and that's a big subject!
Start here: Some guidelines for posting questions in the forums[^] and then read this: Tales from the Evil Empire - Asking questions is a skill[^]

Then think about what you are trying to do, and what is preventing you from doing it. Begin to frame a question around that, so that it gives the reader enough information to start understanding where you are at the moment. Then Google! Then refine your question, and maybe post it. Think first, think again, then ask!

But just going "it don't work" isn't helping anyone: not us because we have no idea where to begin answering, not others with the same problem as you because they can't find your question and recognise it as the same problem, and not you because you can't get a useful solution!
   
Python
124   if urlparse(chegg_url).hostname != 'www.chegg.com' or ctx.message.channel.name != "general":'767066491673640970'

A glance at the code will tell you that "general":'767066491673640970' is not a valid string.
