ERRORS

new():
        From Mo::utils::check_array_object():
                Parameter 'property_snaks' must be a array.
                Parameter 'references' must be a array.
                Property mediainfo snak isn't 'Wikibase::Datatype::MediainfoSnak' object.
                Reference isn't 'Wikibase::Datatype::Reference' object.
        From Mo::utils::check_isa():
                Parameter 'snak' must be a 'Wikibase::Datatype::MediainfoSnak' object.
        From Mo::utils::check_required():
                Parameter 'snak' is required.
        Parameter 'rank' has bad value. Possible values are normal, preferred, deprecated.
