How to debug views_handler_field_node_revision handler? I believe I have updated some of my modules, then the following debug message pop on the calendar page. Does anyone know what is this message and how to solve it?


  Debug:
  
  
    'Handler views_handler_field_node_revision tried to add
    additional_field nid but node could not be added!'
  
  
  in views_handler_field->add_additional_fields() (line 142 of
  /public_html/sites/all/modules/views/handlers/views_handler_field.inc).
I had this problem when the "Content revision: Title" field on my view was set to "Link this field to the original piece of content" however it wasn't using the relationship to the content.

I set it to use the "Content revision: Content" which fixed the link and the error.

I think this error is displayed with problems regarding a node_revision view and an error in the relationship, as Nels mentioned.
