the spec.initialConfig field is empty:

initialConfig:{}

Expected Behavior

No response

Steps to Reproduce

No response

Additional information

initialConfig:{} field is always set default values in logset webhook, so it should never be zero value {}, this may be caused by uninstall mo-operator just after creating logset, and its webhook is not executed, after reinstall mo-operator, this issue will happen.

will investigate this issue more deeply and consider whether there is a good way to solve this problem
