Vert.x: PostgreSql result containing DateTime not getting added to JsonArray - postgresql

Question

I have a sql query which returns DateTime as one of the objects. I am getting an error when it is being to added to JsonArray.
Stack Trace:

I believe the error is occuring here:
private List<JsonArray> rowDataSeqToJsonArray(com.github.mauricio.async.db.ResultSet set) {
List<JsonArray> list = new ArrayList<>();
set.foreach(new AbstractFunction1<RowData, Void>() {
#Override
public Void apply(RowData row) {
list.add(rowToJsonArray(row));
return null;
}
});
return list;
}
My Rowdata looks like this:
Some(MutableResultSet(ArrayRowData(, , hphan, 2016-04-26T00:00:00.000-07:00, 1), ArrayRowData(, , hphan, 2016-04-28T00:00:00.000-07:00, 2), ArrayRowData(BXBSVA, BLUE CROSS BLUE SHIELD VIRGINIA, null, 2016-04-26T00:00:00.000-07:00, 1)))
Does anyone know how to fix this ?

Answer 1

This should work with the upcoming release 3.3. However note that the asynchronous client is marked as technology preview so there are rough edges.
Having that said if you need more features that I'd suggest to use the jdbc client instead. While not so high performance it is feature complete.
