What happens if I don't specify a namespace? Does this modification have any impact?

Hi @AlexsJones @matthisholleville

There is also a test for this scenario available at https://github.com/k8sgpt-ai/k8sgpt/pull/1355/files#diff-706f327858423a4a923b82da6299c0c3a0d52e28d13cc24ef493eacf4fef456aR96

If I do not specify a namespace, it will return results from all namespaces.
