It++ std::variant is valueless, possible Iterator problem

void list_nodes(mgp_list args, mgp_graphmemgraph_graph, mgp_result result, mgp_memorymemory) { mgp::memory = memory;

mgp::Graph g(memgraph_graph);
const auto record_factory = mgp::RecordFactory(result);

    while(pIt != props.end()) {
        auto record = record_factory.NewRecord();
        record.Insert("id", id);
        record.Insert("property_name", pIt->first);
        record.Insert("type", TypeToString(pIt->second.Type()));

User provided us with this code of their custom QM function. When using it++, a std::variant is valueless exception is thrown. This happens when it++ is called for the second time. When using ++it, everything works good. This could happen because something is missing from Cpp API?
