Not able to run Sample component plugin in on-premise environment

We are able to successfully install map field component plugin(downloaded from link--https://github.com/appian/integration-sdk-examples) on on-premise environment but we are not able to load map on the interface side

We have google map key generated and used in this component as well.

We are using below sample code in interface to display the map 

load(   local!location: "the white house",   local!pin,   {     mapField(       label: "Map",       height: "AUTO",       key: "AIza...5vE4",       location: local!location,       pinValue: local!pin,       pinSaveInto: local!pin     ),     a!textField(       label: "Location",       value: local!location,       saveInto: local!location     ),     a!floatingPointField(       label: "Pin Latitude",       value: local!pin.lat,       saveInto: local!pin.lat     ),     a!floatingPointField(       label: "Pin Longitude",       value: local!pin.lng,       saveInto: local!pin.lng     )   } )

Environment Appian version used -22.3

component plugin zip attached.appian-component-plugin.zip
