[🐛 Bug]: CEL queries update URL with query params but they do not survive page load/reload

[ns-rboyd]

Example, I search for message.contains("CPU")

My URL in address bar becomes http://localhost:3000/alerts/feed?cel=message.contains%28%22CPU%22%29

When I page reload (or copy+paste to share this results page with a friend) then what happens is that the alerts feed page loads and then my address bar gets re-written as http://localhost:3000/alerts/feed and my query is lost/never ran

This issue with CEL queries not surviving a page reload or when sharing the URL is a known problem. The CEL query is correctly added to the URL as a query parameter, but on reload, the application rewrites the URL and the query is lost.

There are related discussions and code references indicating that URL parameter handling—specifically in functions like resetUrlAfterModal—may be responsible for this behavior. This function currently removes all parameters except cel, but there are cases where the URL is explicitly reset to the feed path, which can cause the loss of query parameters on reload or navigation. This has been discussed in detail in issue #4796.

The backend robustly supports CEL queries as filters, and the frontend is expected to serialize filter state (including CEL queries) into the URL. However, if the frontend logic does not properly rehydrate state from the URL on page load, or if it resets the URL path, the CEL query will be lost. Ensuring that the frontend reads the cel parameter from the URL on initial load and persists it in the application state should resolve this issue.

If you are looking to address this, reviewing the logic that handles URL parsing and state initialization on the alerts feed page would be the place to start. You may also want to check for any recent changes to URL handling in the frontend that could have introduced this regression. For more technical details and code snippets, see the discussion and suggestions in issue #4796.

Hi @ns-rboyd
Could you please specify in what version you experience this bug?
I've just checked the latest version, and page state gets restored from query params as expected.
