Type 'Promise<void>' is not assignable to type 'Marker'. Property '_objectInstance' is missing in type 'Promise<void>'. Ionic 2

I tried to apply what is in the docs gor the google maps in ionic 2 as it is in the official site: Ionic Docs Google Maps

I got this error: 

Type 'Promise<void>' is not assignable to type 'Marker'. Property '_objectInstance' is missing in type 'Promise<void>'. Ionic 2

try this:

 map.addMarker(markerOptions)
   .then((marker: Marker) => {
     marker.showInfoWindow();
   });

instead of

 const marker: Marker = map.addMarker(markerOptions)
   .then((marker: Marker) => {
     marker.showInfoWindow();
   });

I had this error too, and the solution i've found is to not use marker variable, but only write

map.addMarker(markerOptions).then(...)

And it works, my marker was displayed.
