Hi,

I got custom authors component from the predesessors wich started to show followin error message in the Studio - Components - Preview interface:

 

Freemarker template 'preview' processing failed:
InvalidReferenceException:The following has evaluated to null or missing:
==> env.context.message  [in template "preview" at line 1, column 6]

What can I do fix the error? Code of the custom component:

    If you want to test in studio do something like this

     

    (env.context.message.id)!'19'

    That way if env.context.message is null, it wil set it to whatever you want (my example is 19.
