Troubleshooting

[mrCherry97]

there is probably problem with polling when the backend is throwing error, need to add error to this if: https://github.com/kyma-project/busola/blob/main/src/shared/hooks/BackendAPI/useGet.js#L103
need to try to fix the silentRefetch function

I have observed the same issue. It appears that in the event of an error, the clearInterval(intervalId); function is not called, leading to the continuous creation of interval functions. This continues until all resources are exhausted.
