I have synced leads to SFDC queues without issue. Now we have logic built to route leads to individual lead owners. Upon conducting initial tests I get a "Failed: SFDC user with name '_____' not found" message in the results tab. I am trying to troubleshoot possible causes and haven't come up with anything yet. I am hoping someone might be able to point out what I am missing.
I offer donuts in exchange for your brain power.
