Redhat Subscription page issue

Problem:

We have upgraded to Foreman 1.20. Every thing is working fine with one exception. When I go to subscription it lists all of our subscriptions fine. But when I click on any of those subscriptions to see who they are attached to all I get is a blank page. When I look at the page source it has loaded a page and I get a status 200. But the page is completely blank. There is no data in the source.

Expected outcome:

If I remember right it should show a page with the hosts that are using that subscription.

Foreman and Proxy versions:

Foreman 1.20, no proxy

Foreman and Proxy plugin versions:

These are the Candlepin versions.

I tried a reimport to see that would help and it didn’t. I checked the production logs and I don’t see any obvious errors even in debug mode.

Any suggestions would be greatly appreciated.

Thanks

I am having the same problem.
According to someone on IRC (I cannot remember who that was) this is a known bug and a fix is in the working.
As a workaround until a fix is actually available, you can replicate the subscriptions in the URL with legacy_subscriptions (e.g. https://example.com/legacy_subscriptions/386). That loads the legacy subscriptions page, witch is in old UI style but at least works.

This is being tracked in Bug #25572: blank page on navigating from foreman to katello page - Katello - Foreman and the fix is being worked on.

Thank you to both of you for the info. I can stop banging my head against the wall now.

As a workaround you can use the api link to the subscription. This way you can get the information needed in JSON

This was actually Bug #25515: Subscription detail page is empty - Katello - Foreman and it’s now fixed via:

https://github.com/Katello/katello/pull/7994

The problem was a $ in the URL part which wasn’t an actual regex. That means you can use the URL /subscriptions/1$ where the application links to /subscriptions/1. It looks like there may be a difference in nodejs handling that made it work in development but not in production. The fix removes the $ from the “regex”.
