Code looks good, Do you remember what actions showed the leak?

@MariaAga It appeared when I was working on this PR and clicking on the chart or changing the dropdown filter, but I haven't tried any other ways.

Pull Request Overview

Fixes a memory leak in the TemplateInvocation component by replacing a shared intervalId with a useRef-based interval tracker and ensuring all polling intervals are properly cleared.

• Use useRef (intervalRef) instead of a module-scope intervalId to store the interval handle.
• Update error handler and effect cleanup to clear intervalRef.current.
• Ensure cleanup logic runs on unmount and when polling should stop.

Comments suppressed due to low confidence (1)

• [nitpick] Consider adding unit or integration tests to verify that the polling interval is cleared when the component unmounts or when finished becomes true, to guard against regressions.

}, [finished, autoRefresh, setAPIOptions]);

After calling clearInterval, assign intervalRef.current = null to reset the ref and avoid clearing the same interval repeatedly on future renders.

Probably not related to this pr, but when I tried to changing the dropdown filter and then back to all statuses the table is empty (only when autoreload is true)

@MariaAga, the error always appears once after calling /api/job_invocations/id/hosts.

Probably not related to this pr, but when I tried to changing the dropdown filter and then back to all statuses the table is empty (only when autoreload is true)

I don't know how to reproduce it, but I agree that it's probably a separate issue.
Would it be okay to merge this PR, and we can investigate the filter behavior you're seeing later?

[MariaAga]

The issue I described can be solved in another pr yes.
I cant reproduce the issue without the pr, but again, code look good
