custom code blows up when printing output of v8::JSON::Stringify

[Jeff Greer]

I have a set of static configuration properties that are exposed. These properties are set to defaults in my c++ code. They can be changed in a Javascript script. String and integer types seem to work correctly, but when I have bool data things go south quickly. When the bool data is set to 'true' the program finishes but the bool properties do not appear in the contents of v8::JSON::Stringify. When the bool data is set to 'false' the program blows up if the configuration object is printed using my custom console.logging functions.

        if(value->IsObject()) {
            auto json_string_value = v8::JSON::Stringify(isolate->GetCurrentContext(), value);

std::string string_value = slim::utilities::v8StringToString(isolate, json_string_value.ToLocalChecked());

        }
