[2.5, UI] Error adding ssh keys for new users: TypeError: Cannot read property 'sshkeys_count' of null

[Björn Tillenius]

Testing with 2.5.1-7489-g2f25a2cc0-0ubuntu1~18.04.1 and RBAC enabled, I often have problems getting passed the intro page. After successfully adding my ssh keys (lp:bjornt), clicking on "Go to dashboard" doesn't do anything.

Looking at the JS console, I see this error:

I cant't seem to replicate the issue, although I have set up RBAC/Candid with Ubuntu SSO. Is this still happening for you, Bjorn?

[Björn Tillenius (bjornt)]

I haven't tried it lately, but I could give it a try to reproduce it again next week. Note that it didn't happen all the time.

[Alberto Donato (ack)]

FTR I could reproduce the issue without rbac enabled, just right after installing maas

[Alberto Donato (ack)]

this can easily be reproduced in master by stoppingat the "add ssh keys" page at the first user journey. it doesn't always happen, but a few page reloads should show it.

The reason for it is that the $scope.user in intro_user.js can be null, because UsersManager.loadItems calls this._loadAuthUser() but doesn't actually way for it to complete, so the _authUser can still be null when the function returns (and gets propagated as such).
