Attempting to download books that don't need to be borrowed results in an error

[darnn]

For books in the public domain, etc. For example, trying to download this: https://archive.org/details/dli.ernet.247978 Gives this error: Something went wrong when trying to borrow the book, maybe you can't borrow this book <Response [400]> {"error":"You do not currently have this book borrowed."}

Granted, on the book's page you can simply download a zip with the individual images, but if I'm just copying the URLs of several books, I'm usually not checking individually whether they need to be borrowed or not. In the case of this author, for instance, this book does not need to be borrowed, but the rest do: https://archive.org/search.php?query=creator%3A(Mure%20Pierre)%20AND%20mediatype%3A(texts)

for anyone looking for a hack fix around this comment out line 199. #session = loan(session, book_id) but it would be better to first check if the book needs to be loaned instead as the original commenter suggested.
