FTS5 content table bug

I try TSQLRecordFTS5Unicode61 with FTS4WithoutContent.
Table and triggers are created but any insert raise exception docid column don't exists in search table from insert trigger.
Reading FTS5 documentation i make this changes. Main diffeence, FTS4 use docid, FTS5 use rowid.
