I am trying to serve images stored in cloud storage from appengine python
Standard environment.
I found the images.get_serving_url() to be the simplest way to do this after
some research. But, unfortunately it did not work when deployed.
Here is the error message. Am I doing something wrong in this call. Or this
method is not the correct one for this use. Is there any other simpler way to
achieve this?
return images.get_serving_url(None, filename='/gs/' + self.get_filename())

"/base/data/home/runtimes/python27_experiment/python27_lib/versions/1/google/appengine/api/images/__init__.py",
