I get the following error when running GNOME Books. I am not sure if it
is a warning or an error. Gjs tags it as a warning but JS treats it as
an error with an exception.

I am filing it here, for now. If I get a fix, I'll post on this bug.

Are you still having this issue?  It's working for me and the upstream bug
report https://bugzilla.gnome.org/745741 has been closed as unreproducible.

can't really verify it.

In previous version (3.18) where I reported it, it was able to render epub
format. Now (3.22), it doesn't really render anything at all. Just blank pages.


If you have further interest in Books, you may look at my other bug report [1],
for some additional context.

But, for the sole symptom of this bug report, yes, it is no more reproducible
with 3.22.

PS: As mentioned in the referenced bug report, it is odd that GNOME Docs renders
   pdf and other documents well, whereas Books does not.

It's strange that epub doesn't work for you.  I tried an epub file from
http://www.gutenberg.org/ebooks/375 and it worked, though zooming is not
implemented which makes it much less useful.
