CV-UI: creating filter rules results in "Something went wrong while creating the filter!" error
On my machine, specifically on Firefox, creating filters results in the error above. The filter is created, but I get redirected to the filter list page instead of the filter details page. Also, when testing out the errata date filter PR (https://github.com/Katello/katello/pull/9683), the POST request to create the empty filter rule was missing. This worked with Chromium, however.
There was one issue with Chrome which might be related. Sometimes I'm not redirected to the filter details page. When I am, after a few seconds, I'm redirected back to the filter list page.
One potential cause is latency between the browser and the API. I'm using a SOCKS proxy to browse my VM webservers from my desktop computer to my server, which could be related. However, this did work for me at one point when testing the above PR, so the issue may be transient.
