What exactly do you mean it does not work? 🤔 We checked it locally, right? And it was working fine, isn't it? 🤔🤔🤔

Need test cases

@monkeyDluffy6017 I could not understand what kind of extra test case is needed. I think the existing test cases are sufficient.

@shreemaan-abhishek I mean the syslog encoding error. so the log server such rsyslog can't receive the log entry.

aha. now your commit has been copy to #9425
