Hi all - I installed the custom-category-boxes theme component, and on some (but not all) of my pages, I receive a warning banner at the top and see the following in my browser console. It appears that this is because the c variable ends up being null–why that is, I did not investigate further.

client-error-handler.js:125 [THEME 2 'Custom Category Boxes'] 
TypeError: Cannot read properties of undefined (reading 'name')
    at category-banner.js:31:24

reportToConsole	@	client-error-handler.js:125

At first I thought this may be due to the category names having spaces in them, but even renaming one category to have no spaces continues to throw this error.

Happy to provide more information if wanted/needed. The forum in question is https://forums.rockylinux.org

Can you share pages where it happens?

I also noticed an Uncaught TypeError: Cannot read properties of undefined (reading 'name'). But it isn’t related to custom category boxes; it even happens in safe mode.

When I open https://meta.discourse.org/u/chapoi/invited/redeemed?safe_mode=no_themes%2Cno_plugins in a new window or tab, I get this:

Error
Error1087×946 215 KB

It does not happen when I remove ‘redeemed’ from the URL, and I was not able to reproduce it using a staff user.
