描述

triage me type: bug

I need to call GeocodingApi.reverseGeocode from with a java app running in an GCP app-engine. My code looks like:

context = new GeoApiContext.Builder(new GaeRequestHandler.Builder())
.apiKey("").build();

LatLng location = new LatLng(posLat, posLong);
GeocodingApiRequest request = GeocodingApi.reverseGeocode(context, location);
GeocodingResult[] results = request.await();

Running this code gives the exception:

I updated all my recources (especially google-dependencies) to the latest available versions. I also use the latest image for the GCP app engine. But still the error persists.

I guess that this issue is related to https://github.com/googlemaps/google-maps-services-java/issues/672, but there another language and API-call is used. Therefor I'm raising a new issue.

Help is urgently appreciated... Thanks a lot!
