json::value RCamCfg::GetCfgValue(const std::string& key)

{

                try {return config_.at_pointer(key);}

                catch(...) {

                                json::value x;

                                return x;}

}

bool RCamCfg::SetCfgValue(const std::string& key, const json::value& val)

{

                try {config_.set_at_pointer(key, val);}

                catch(...) {return false;}

                return {true};

}

The first function compiles and runs but the second fails to compile with the following:

error: 'class boost::json::value' has no member named 'set_at_pointer'; did you mean 'at_pointer'?

config_is defined as “json::value config_;”

Any ideas what I am doing wrong?

Thanks
