Google mapsKey generates a warning!

Solar2D Corona APIs
#1

I’m getting this error message when I build my app:
WARNING: unrecognized key: settings.application.license.google.mapsKey (string)
I’ve added my Google mapsKey to my build.settings as detailed on this Solar2d page:

https://docs.coronalabs.com/api/library/native/newMapView.html

Why does Solar2d not recognize this setting?
I’ve remove my map key from my settings listed below.
Thank you in advance. ~Keith

   application =
   {
    license =
    {
        google =
        {
            mapsKey = "xxxxxxxxxxxxxxxxxxxxxx",
        },
    },
   },

As stated in docs, the mapsKey goes in config.lua

Embarrassing! Yes, thank you for your reply!
