You can view the appropriate Github page <https://cloud.google.com/appengine/docs/flexible/custom-runtimes/build> for the base App Engine Flexible Docker image that you are building on to find out what changes have been made to your specific image since you last deployed.
I see that gcsfuse is able to handle authentication on App Engine <https://github.com/GoogleCloudPlatform/gcsfuse/tree/master/vendor/golang.org/x/oauth2/google>, so this might be an issue with gcsfuse not being up-to-date with the new App Engine Flex images. Since gcsfuse is open source it is recommended to report this issue to the engineering team on their Issue Tracker <https://github.com/GoogleCloudPlatform/gcsfuse/issues?utf8=%E2%9C%93&q=>. - Note that Google Groups is reserved for general product discussions and is not intended for technical support. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
