ERROR: nil is not of type graphics-ports:font-description when accessing slot graphics-ports::attributes.

Hi - I'm very new to open music, but whilst exploring the examples of a few external libraries (OMChroma, OMChant), I'm encountering this error whenever the patch uses a certain type of box.
ERROR: nil is not of type graphics-ports:font-description when accessing slot graphics-ports::attributes.
The ones I have noticed it with are CS-ARRAY & CH-FOF. This error happens whenever they are in Mini-View mode (also mini view mode doesnt work for these objects - the box just becomes blank)
Whilst I know these are external libraries - they are two separate libraries and so I think the problem may be more deep rooted than just the libraries themselves.
Any help in resolving this issue?
I'm happy to provide as much info as needed to diagnose the issue

Hello, sorry for the late reply. I think I need to update the OMChroma and OM-Chant libraries.

Actually I think it's a bug in OM# 1.7.
Here is a hotfix: fix-array-miniview-1.7.lisp.zip
→ Unzip and install the lisp file in the "Init" folder that you will find in the application bundle.
