Why do I get 'Could not resolve the subpath “{slug}” after trying to add a category select to a Neo field? I tried to add a Category Select field into a Neoblock but when i first saved the entry I received the following error:


  Internal Server Error 
  
  Could not resolve the subpath “{slug}”.


I removed the Neo Block with the Category Select but the error persists.

Any ideas?
i removed {slug} altogether from an Asset field definition.
