Conversion of type 'Mock<Promise<MapsLibrary>, [], any>' to type '{ (libraryName: "core"): Promise<CoreLibrary>; (libraryName: "maps"): Promise<MapsLibrary>; (libraryName: "geocoding"): Promise<GeocodingLibrary>; (libraryName: "streetView"): Promise<...>; (libraryName: "maps3d"): Promise<...>; (libraryName: "places"): Promise<...>; (libraryName: "routes"): Promise<...>; (libraryNa...' may be a mistake because neither type sufficiently overlaps with the other. If this was intentional, convert the expression to 'unknown' first.
