I work with WGLMakie and Observables and stumbled on this error.  
I had perfectly working function but suddenly I started to get this error. It is very long and it even do not show at which line of my code is the problem.  
I observed what it doesn’t happen when i delete line where I run f (f = Figure()) or pass observable. Any ideas what could be the problem?
