I have a problem with uploading a document

Hi,

When I want to upload a file it does, not say any issue, but when I tell it to summarize it or something it simply tells me to upload the document.

Then I tell it that I have done that and gives me the following:

“It seems that I don’t have the ability to receive direct file uploads. However, if you can copy and paste the table of contents or the text containing the chapter names, I can easily help you extract them. Let me know how you’d like to proceed!”
