This seems to be an error that is being passed from the data source, Presto, and not Tableau itself. I know the server might be running as expected but I would double check a few things.
+ Is the latest version of the database driver being leveraged to connect to Presto? Does using the prior version allow for the connection to work as expected?
+ Does this error occur when dragging and dropping the new measure into the view?
+ Does this occur during an extract refresh?
