encountered JAVA com.google.apphosting.api.ApiProxy$CallNotFoundException when using geocoding in GCP app-engine #682

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:

A 2020-05-14T17:42:52.557941036Z com.google.maps.errors.UnknownErrorException: Unexpected exception from com.google.apphosting.api.ApiProxy$CallNotFoundException: Can't make API call urlfetch.Fetch in a thread that is neither the original request thread nor a thread created by ThreadManager

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!

Think the root cause might be missing EnvironmentFactory stated in ApiProxy.java. envFactory is null. 

        ApiProxy.Environment threadLocalEnvironment = (ApiProxy.Environment)environmentThreadLocal.get();
        if (threadLocalEnvironment != null) {
            return threadLocalEnvironment;
        } else {
            ApiProxy.EnvironmentFactory envFactory = getEnvironmentFactory();
            if (envFactory != null) {
                ApiProxy.Environment environment = envFactory.newEnvironment();
                environmentThreadLocal.set(environment);
                return environment;
            } else {
                return null;
            }
        }

Or do not use Google App Engine client library. 

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