• Describe the feature in as much detail as possible.
  when run a code like:

void test(const nlohmann::json& a) {
    cout << a["a"] << endl;
}
int main() {
    nlohmann::json a;
    test(a);
}

It just assert fail with no log or hint of the error key. When the project is quite complicated, it is hard to know where i got wrong.
