I am trying to send campaign attributes like no. of emails sent,opened, link clicked to analytics for each delivery for common reporting. I have done all setup as mentioned in the document. But there is no data flown to analytics account. When I checked technical workflow in campaign , found that it is getting error out at 'sending campaign attributes' as shown in below screen shot. I think this is the problem. Please help me to clear this issue and also suggest me if there could be some other problem as well.
