It seems that I have discovered a bug by an accident.
I have a "AM2302" sensor. When the sensor is disconnected, the json prints nan without double quotes for the missing values:

Here is more relevant discussion:nan IS a numerical value: https://en.m.wikipedia.org/wiki/NaN.
In computing, NaN, standing for not a number, is a numeric data type value representing an undefined or unrepresentable value, especially in floating-point calculations.
So I don't find it to be a bug.
https://jsonlint.com/Finite numbers are stringified as if by calling ToString(number). NaN and Infinity regardless of sign are represented as the String null.
