I want to add, edit, and read content in a nested vector and map

typedef std::map<std::string, std::any> T_map;
typedef std::vector<std::map<std::string, std::any>> T_vector;

T_map data;
data["Total"] = 50;
data["Name"] = std::string {"abc123"};
int Total = std::any_cast<int>(data["Total"]);//read
std::string Named = std::any_cast<std::string>(data["Name"]);//read

data["Functions"] = T_vector(50); //initialized with size 50
std::any_cast<T_map>(std::any_cast<T_vector>(data["Functions"])[0])["addr"] = 123456; //There are no data changes
int addr = std::any_cast<int>(std::any_cast<T_map>(std::any_cast<T_vector>(data["Functions"])[1])["addr"]); //read error 

I think this error is because adding information in line 11 was not as expected, leading to an error in the code in line 12.
terminate called after throwing an instance of ‘std::bad_any_cast’
what(): bad any_cast

Is there any other solution or alternative that is more understandable?
