Additional context

Hi Team,

I am unsure if this is bug or not, I can see the posted metric as log where I am running this binary, just wanted to confirm if this expected output. Thank you.

Yes, this is the expected output. If some data couldn't be indexed, the errors would show up.
Any data without errors is indexed.
