Hi Sowmya,

I was seeing the logs from LS/hLS and the following lines are appearing:

Could these errors influencing in the summarization process?

Thanks,

Hi Herbert,

I think there is some issue with the hLS summarization. Your hLS appears in
the gLS but there is nothing in the summarization info. I have attached the
output for your reference.

Hope this helps!
