GCS Extension only provides Listfiles, but does not work for Download

[dinogregorich]

Has anyone had success using the download feature of the GCS Extension?

It is not behaving like the example documented on the APIGEE site. https://docs.apigee.com/api-platform/reference/extensions/google-cloud-storage/google-cloud-storage-....

I use a extension callout to get a list of files from Google Storage. That is successful, and I am able to get the list in order to check it to see if the requested file exists (listfiles). Then I use another extension callout to retrieve the file (download). However, using an extension callout policy to download (not list) a file from Google Storage, the Output is not established, it does not get created and therefore errors when I check it for the file. The response body is empty, but the ConnectorCallout.response is loaded with some but not all of the file content.

I had APIGEE support try to help, but they have not yet identified if it is a bug or not, but no matter, it does not work as the documentation describes, and after many hours of trial and erro, we cannot use it. Maybe @Dino-at-Google will know something about this?
