PubSub push subscription error: The supplied HTTP URL is not registered in the project that owns the subscription

[jeremykeen]

When creating a push subscription for this app, I get the error below caused by the addition of the "-preview" to the address by the GAE Flexible environment. Removing this allows me to create the subscription but then I get redirect responses. Is this the correct behavior or does appspot-preview.com need to be added somehow?

The supplied HTTP URL is not registered in the project that owns the subscription (url="https://<app-id>.appspot-preview.com/pubsub/push?token=1234abc", project_id="<proj-id>").

In which file did you encounter the issue?

python-docs-samples\appengine\flexible\pubsub\

This is a known issue and unfortunately pub/sub push notifications to flex will not work until the redirects are removed.

[jeremykeen]

Ok, if that is the case, does the sample python app need to use flex as specified in the app.yaml?

I'm not sure what you're asking.

[jeremykeen]

The sample app that receives push subscriptions uses App Engine Flex which does not work with pub/sub.

[theacodes]

I'm still not completely clear on what you mean, but the sample app will remain as-is in anticipation of the infrastructure bug being fixed.

[jeremykeen]

What is the timing of the redirect removal? Until then, the sample app code does not work with pub/sub because it leverages App Engine Flex.

[theacodes]

No timeline, but it is a high priority issue.

[theacodes]

The redirect should be resolved now, closing.
