Google map for geoPoint shows as a Grey Box

[faizanabidnaqvi]

Based on another issue reported, I was able to show the geoPoint field by including the places api script. The places text box works fine but the Google Map below it shows with a grey background, although the rest of the map UI is there.

I'll be thankful if there is a solution to this. Alternatively, is there a way to include a custom field for the map that we can use from another module in react?
