EmptyValueError

exception wikibaseintegrator.wbi_exceptions.EmptyValueError

Bases: ValueError

Raised before a write when a claim, a qualifier or a reference has no value, while its snak type states that it has one. A datatype created with None or an empty string as value has no value, and the Wikibase instance would reject it with a less explicit error.

Set a value, or use the WikibaseSnakType.NO_VALUE or WikibaseSnakType.UNKNOWN_VALUE snak type.
