Unexpected token JSON

Hi, Guys!

I have an issue with query like this:

        SELECT i.*, 
          array_agg(m.name) as motifs,
          array_agg(m.global_art_style) as global_art_style,
          array_agg(m.styles) as styles 
        FROM public."Location" as i
          LEFT JOIN public."Motif" AS m ON m.location = i.id
          WHERE 1=1
        GROUP BY i.id
        ORDER BY id ASC

Inside array_agg fields I have text with possible NULL values, it is fine in PgAdmin and I see just NULL values, but with your library the query is failed with error:
Unexpected token N in JSON at position 0

No file, test, or entry point is named. Reproduce the shown PostgreSQL query through Postgres.js and trace how array_agg results containing NULL are decoded; the expected handling of those values needs clarification before a completion check can be defined.
