Error: Tableau Output: Must Pass at least one table

[Rkornack]

Hi community! 

I'm getting the following error in Alteryx when trying to publish to tableau server. (The thing is, though, I'm using the SAME Tableau tool configured the SAME way and it's working for other outputs! The browse tool immediately before the Tableau output tool is populated, and I've tried inserting a select tool before the tableau output. Any idea what could possibly be going on???!!!

Assuming you're using a Tableau PAT to authenticate, issue is that a PAT will only support a single request/session at any given time. You'll need to create another PAT to use on the other TabOutput tool or build out your workflow in such a way to control when the 2nd one starts using the block until done (not foolproof) or if on a newer version, control containers.

Thank you SO much! I appreciate you sharing your knowledge :) Your solution worked, I didn't need both Tableau outputs anyways.

I had this same error pop up, but I only had one single output.  The only way I was able to resolve the error was to add a data cleansing tool right before the Tableau Output tool.  It seemed as though with the data cleansing tool, it allowed the workflow to 'complete' (without the writing to Tableau piece) before starting to overwrite the table in Tableau.
Possibly a 'Block until done' tool right before the Tableau Output tool would have done the same?!
