Having problem returning future from cppcoro::generator

[Xyncgas]

cppcoro::generator<std::optional<std::futurestd::string>> object_list (std::string* input)
{
...
co_yield {};
...
while(...==true)
{
co_yield (std::async(std::launch::async, = {return HttpGetString_convertedTo_stdString(target); }))
}
}

int main()
{
for (auto element : object_list(a)
{
//Object_list showing error in visual studio
}
}

I am not a very good github user please forgive my formatting, I was exploring on my own and wanted to do something like this and I can't fix it

nvm, I feel like shared_future is needed for supporting this, please close the repo after reading it
