Did you happen to find an answer? I received this error and determined it to be a problem with a nested IF statement. Once it exceeded 9 levels, it began returning this message. I put the logic into the stored procedure source (and removed it from Tableau) and the issue resolved.
One last note...Tableau also did not like the logic - in this case a CASE statement in TSQL - in the final select of my stored procedure. I had to create a temp table using the logic and then select from the temp table.
Hope this helps!
