Code is looking forBody

I get this error message
Notice: Undefined index: body i sheetnode_views_data_alter() (rad 150 av ...public_html/sites/all/modules/sheetnode/sheetnode.views.inc).

This is from a fresh install of the Sheetnode module, and regardless of whether there are any Sheetnodes or not.

A workaround is to create a new field 'Body', then the message disappears. But I don't want any Body...
