Hi there! Thanks for the screenshot! :D
So, put that little patch below the Eli Book plugin and see if it will work:

If yes, then I will add it to the Eli Book. If not, show me the screenshot of the new error.
It appears to do the same error again, I appreciate you trying to find a fix even if I just need to give up on furniture if no fix can be done
