I am trying to update a Smartlead campaign, what is the below error?

Hey Ram, I looked at the 4 "Update Lead in Campaign" columns in your table, but none were displaying the error at the time of my check. Most were simpy "missing input". If you see this again, please let me know, and I can have a look with you.

I think you might have what you need at this point. I'll tentatively mark this closed for the moment, but keep in touch if you hit other roadblocks.
