I am initializing this object in register function and accessing this in different functions defined in same shared library. While accessing in different function, it doesn’t hold initialized data. This is failing in my storagecommands.cpp for IPMI.

Looks like there are some header included in existing file is messing it up but I have no clue yet. This only happens with json object.
