BUG: With METHOD SLEEP deleting configmap does not delete the file.

[ns-phegde]

I'm having issues with METHOD: "SLEEP". I'm getting the below error when I use something like the config I've specified. To be more precise this happens when a configmap is deleted.

Version: v1.25.2

ERROR:

Traceback (most recent call last):
