I am using the nlohmann parser to parse a json string, but my code is crashing.
My code
const std::string& dataStr; //I receive dataStr as a parameter, this is just to show type of dataStr
std::string jsonString(dataStr.c_str(), dataStr.c_str() + dataStr.length());
nlohmann::json jsonData = nlohmann::json::parse(jsonString);
I am getting dataStr as a parameter.
The call stack I am getting is

lohmannjson.hpp line 11619, parse error - unexpected.
The error is not reproducible for all jsons, that's why I want to know what does the error mean? Also can it be because the string I am parsing is too big(~20K chars). Any help appreciated, thanks in advance.
