v8::FunctionCallbackInfo<v8::Value> const& info GetReturnValue().SetNull(); Does not work

[Pradish]

V8 Version: 13.1.201.19

static void getProperty(v8::FunctionCallbackInfo<v8::Value> const& info)
{

//Business logic 

//property was not found in the internal list 

//setting the returnvalue to null using

info.GetReturnValue().SetNull();

}

But in the javascript code
var result= process.getProp('some.property');

the result is always undefined on Linux , whereas on Windows it works as expected, that is it returns null.

any idea what might have caused this issue, does anyone think this is an issue with V8 on RedHat Linux. i do not see this behaviour on 13.0.245.18

Thank you for looking into this.
