[Python] Sometimes getting the wrong destination when using google maps distance_matrix API

I have a python script that uses distance_matrix from the Google Maps API (yes I know this is now legacy and replaced by routes, but I'm updating an older piece of code and don't really want to change over yet).

My script sends a list of zip codes in Massachusetts as the origin point to get the distance to a destination.

gmaps.distance_matrix(zips, destination, mode='driving', region='us', traffic_model='best_guess')


90% of the time it works just fine, but occasionally it returns VERY wrong results. For example, for zip code 01033, which is Granby, MA it returns a result for Kyiv, Ukraine. If I search for 01033 in maps.google.com it correctly shows Granby. I added region='us' hoping it would try to restrain the results to the US, but no luck.

Any idea why it does this and how to fix it?
