Can't open button group on Catalog Item editing




I can create button group and create buttons inside, but when coming again to Catalog Item to edit a button in my button group, it won’t open. I got an infinite wait without error messages on UI. Watching logs I found below error in production.log:

Did you mean? object

Do you know how to correct that?
