We are also facing the same issue. The version we are using 8.1.
I was doing some analysis on the error and bumped into this mysql page - MySQL :: MySQL 5.0 Reference Manual :: B.5.2.14 Commands out of sync.
Please let us know if you were able to solve the issues by any means?
Thanks and Regards,
Guillermo was only present one day in this forum and that was for the post made here, so you won't get an answer from them I recommend you contact Tableau Support directly.
Thanks Toby for letting me know.
Sure that is the next step I am planning.
