Subject: [PATCH] Handling undefined values

Passing "united states" as a attribute for the geocoder, like
    const data: any = await geocoder.geocode(location);

but getting Error:

return target.apply(this, arguments);
                      ^
TypeError: Cannot read properties of undefined (reading 'View')
