Empty comparison value not accepted and check fails

[darshil4420]

I am working on a project which has been built over kube-bench. It sends the key value pair of flag and its value like as below
flagName: flagValue.

There is one scenario where flagValue is empty string i.e "". I've provided expected value empty string as well and I am using eq operator.

Some how it's not compared and the check is failing.

Can someone please confirm is this expected behaviour?
