Could you provide the code that errors or an example like it?

Of course. For explanation im trying to establish a Manga Database currently im trying to get all mangas from kissmanga. With your module i want to add additional information for the manga that hakuneko does not provide like score, image, description...
Im just starting to learn javascript and node js, if you need more just let me know. Thanks for your tool, and for your fast response.

Sorry for delaying my answer all this time, I'm working on a tight schedule here.

My library do lots of checks and transformations before I can give you an usable data from MAL.

When I read str.split is not a function most like there where a case I was expecting.

Sadly I wont find any time to look carefully onto this soon but your print will be useful.

One thing that could be helpful too is if you know exactly what entry had this error like "when I search for a manga with title 'something'".
