Urgency: LOW Error Message: "AssertionError: invalid value field: value" Code Snippet (summarised): petl.look(petl.recast(petl.empty())) Suggestion: A more intuitive error code or catch this exception

Thanks for reporting this, I'll think of a good way to handle. FWIW there are many places where exception handling and/or error messages could be improved, so feel free to keep posting.
