Incorrect empty state during topic loading in Staging

[nucleogenesis]

Observed behavior

While navigating the staging tree on this channel: https://studio.learningequality.org/en/channels/f3d0bd6dcddd5990bf4b9ed32d71743e/#/staging/09c87bf78fcd4839afc21704a5a56eb1 I do not see any loading indicator between topic navigations. I only see "This is empty" for several seconds while the content loads.

Expected behavior

• Do not show "this is empty" unless we know for sure it is
• Show the same KCircularLoader on the page that you see when navigating a channel in the Library

User-facing consequences

This appears to only affect the navigation for through the staging tree. I've only encountered it on a cheffed channel, so perhaps it isn't as user-impacting as I thought it might be initially.

Steps to reproduce the issue

1. Go to a channel where you can click to view the staging tree (ie, the one linked above)
2. See the empty string rather than a loader

Hi @nick2432, thank you, we assigned you some other issues meanwhile.

@MisRob i would like to work on this issue , if it is open for contribution

As noted, this issue appears to be specific to viewing the staging tree of 'cheffed' channels. @GarvitSinghal47 that situation makes this very specific and more involved in simply reproducing it. You'll have to get set up with another repository, Ricecooker, in order to reproduce this.

While you have the studio server running, within ricecooker you may run the following to 'chef' (generate) a channel:

CONTENTWORKSHOP_URL=http://localhost:8080 python tests/test_chef_integration.py

When you run the above, it will ask you for a token, which can be obtained from the account settings page.

After it completes, you should see a 'Ricecooker testing' channel in your local Studio account and a link near the top Updated resources are ready for review. When you click that link, you enter staging browsing mode.

I've assigned you @GarvitSinghal47. If it's too involved, please let us know so we can unassign you.

I have no problem working on the shared data smoothly. Just letting you know, I'm a bit busy this week, so I'll get to it next week. Appreciate your understanding!
