There is certainly room for improvement Lrenzo, you could probably downgrade that exception to a warning for example.
Looking at String toJSONString(SimpleFeature feature) <https://github.com/geotools/geotools/blob/main/modules/unsupported/geojson/src/main/java/org/geotools/geojson/feature/FeatureJSON.java#L546> is has: Object value = feature.getAttribute(i); if (!encodeNullValues && value == null) { // skip continue; } attributesWritten = true; Does that answer your question? It looks like it skips writing null values when writing json out as a string. -- Jody Garnett On Tue, 16 Nov 2021 at 08:05, Lorenzo Di Giacomo <loridi...@gmail.com> wrote: > Hi all, i have 2 question: > 1) what does setEncodeNullValues do?
