Daniel, In what context are you running this? For example, is this an App Engine 1.9 local emulator run?

[Kamran (Google Cloud Support)]

Hello Paul,

Would you elaborate further on describing your issue? Is your setup a local development? Is it possible to post reproduction steps and code? 

In the meantime, for information on how to get started with Cloud Client Libraries for the Cloud Pub/Sub API and some examples, please visit this article. 

[Yendry Machado]

I have exactly the same problem. Any update ???

Taking a guess here: Pub/Sub has two client libraries for most languages, as described here. The "Cloud Client Library in language X" is the recommended client library for most situations as it is generally higher level and more performant. But it is not supported on AppEngine Standard.  For that environment, we have "API Client Libraries."  So what I think is happening is that you are attempting to use the "Cloud Client Library" on "AppEngine Standard."  You have two options: either use AppEngine Flex instead of Standard OR use "API Client Library" instead of Cloud Client library. We are working to make this better. 

Gory details are here.

I got the answer and when I did - the previous comment also made sense.

That is that the Google Cloud Client Libraries do not work in Google Appengine Standard Environment. 

That could be a lot clearer in the chaotic documentation. Things like the article that you linked me to.

The whole idea that the basic, standard Google Cloud APIs are not part of the standard Google Appengine Environment is so braindead that I did not even consider it. It is like something that you would expect from Microsoft!

It seems that the recommendation is to use the google-api-client-libraries - which are basic and there seems to be actual no example - anywhere on the web - of how to use those libraries to use the pubsub service which is what I want.

And anyway - that also appears to be broken since the way to do service account authorisation in appengine depends on a module in oath2client (oauth2client.contrib.appengine - that is specifically for appengine) is not in the version of oauth2client in the SDK and therefore I would assume thus also not in the standard environment. It also cannot be vendored in since there IS a version of oauth2client in the SDK (please, please correct me on any of this if I am wrong). 

This all makes me think it would actually be easier to access the Google Cloud Services by running on SOMEONE ELSE's cloud platform !!! I would say that it looks like no one is in charge - but as a Xoogler myself I know that there is no one in charge - just a whole load of over worked SWE's running from ball to ball - trying to keep them all in the air!

Paul, I can understand the source of your frustration and can tell you that I, and many others, are trying to make this better.  In the short term, it sounds like what's missing here is proper documentation on how to use the API Client Libraries on AppEngine standard.  Does that sound right?

[Paul Harwood]

That sounds perfectly right :) And some changes to the documentation I was going to try to Feedback ( the difference between "we don't recommend" and  "these libraries WILL NOT WORK in the standard environment" is huge :)

[Yendry Machado]

thanks, worked correctly

This was the exact issue it should be loaded into Flex instead of standard. I did mention it above when I first posted this issue. Glad it helped someone else though!
