What is the error?
"Invalid Location" is normally caused by what's often known as "drift" or "GPS drift." It's stemming from your phone's location service, which is not getting a strong lock on where you're located.
Basically, your phone is recalculating its position based on nearby cell towers and other mobile signals. If you're in a location where that signal is kind of unreliable – in a tall building, between tall buildings, in a basement, in a building with a lot of concrete and metal, and so forth, your phone is not getting a steady lock on its precise location, so you're pinging around the area as far as your phone can calculate.
