[Pharo-users] Citezen bug MessageNotUnderstood: Metaclass>>allMethodsInCategory:

Hi, I'm adding some Zotero[1] integration for my Grafoscopio project, now that I'm preparing a couple of papers for my PhD. For that, I'm using Citezen, but when I try to run the renderers to create bibTeX outputs I got the error "MessageNotUnderstood: Metaclass>>allMethodsInCategory:". How can I solve this?
