Using Open Level

I’m over here trying to learn open level, and I can’t seem to figure how this thing works? It keep telling me that url not found where I’m sure it’s using the correct url . I’m sure a bunch of people ran into this, anybody willing to shar information?

Unfortunately, it doesn’t return a result I don’t want to go around doing a bunch of stuff

Edit: I tried another way to travel to another level and it worked, I want to figure this out.

With some investigating I figured it out, But i want to dig deeper on how it go the name, Please close problem

mind sharing? c++ docs dont cover its usage
