We're erroring when hitting the LP API for the subscription object: https://pastebin.canonical.com/59475/

I'll see if there's another way to get a handle on it.

The problem comes down to us not actually using the Launchpad api version which we specify in the configs, together with the wadllib.application.Applicatiion.lookup_xml_id method at:

http://bazaar.launchpad.net/~lazr-developers/wadllib/trunk/view/head:/src/wadllib/application.py#L1123

which raises a NotImplemented error if the requested resource definition (this_uri) doesn't match the api uri (markup_uri) which, thanks to the debug info saved by django, shows:

markup_uri: URI('https://api.launchpad.net/1.0')
this_uri: URI('https://api.launchpad.net/devel')
