It seems to need the allowextra=yes - assumedly because in the null case I guess a value is being returned by the parser that has nowhere to go.


To support "null" for a data structure the way DATA-INTO currently works, a parser would have to avoid reporting both the name and the value "null" when it encountered "null".

It would be good for someone to open an RFE to request an option to interpret the value "null" as meaning that the name was not reported at all. With that option, individual JSON parsers would not have to have any specific support for "null".

In either case, the countprefix or allowmissing option would be needed to handle the missing data.
