@onatakduman did you find any solution?

I has also the same issue and it happened when I implement folioReader.setReadLocator(readLocator) where readLocator was null, After I added null check the problem was solved. If you are using setReadLocatorListener in your code it is triggered when you are opening the book and for the first time you are opening the book since there is no saved readLocator it comes null.
