BKAgentServiceErrorDomain error 8

About a week ago my Books app stopped opening my epubs and pdf files, instead, it shows this message:


The operation couldn’t be completed. (BKAgentServiceErrorDomain error 8.)


I can access my pdf files using Finder, but my epubs are nowhere to be found. Is anyone having the same problem? Does anyone knows how to fix it?

MacBook Pro 13", macOS 10.15

This is how I solved it:


Close Apple’s Book. 


On “Finder” go to “Go” and from there to “Go to folder”


Type the following:


~/Library/Containers/com.apple.BKAgentService/Data/Documents/iBooks/Updates


You will go to a folder with two files inside. Delete them or, if you want to be on the safe side, move them to your desktop.


Open Apple’s Books. Now you should be able to open your books and pdf files.


Hope this helps.
