Unhandled error in Deferred:

[white-gecko]

I get following error, when I try to publish something to the hub.

Unhandled error in Deferred:

    if len(subscribers):
exceptions.TypeError: object of type 'NoneType' has no len()

Am I doing something wrong or is it a bug?
The tests are running through without any problems.

well, if you look at the location of the error, and how "subscribers" is fetched, you'll see that if a topic has no subscriptions, "subscribers" will be "None", causing the error. Obviously this is not implemented nicely, but just adding subscriptions to a topic before publishing anything solves the issue too.

I still get the same error, even though I have subscribed to the topic before. How can I see which subscriptions are active in the hub? The README says: "The root path is the hub endpoint. There is a preliminary/debug interface if you browse to it.". If I open http://localhost:8123 in my browser I get "No Such Resource No such child resource."

Using the fork of @caedesvvv I don't get this error anymore. But get following error:

Fetching http://localhost/~natanael/myfeed.xml for 1 subscribers

is it because I didn't specify any secret?
