Getting an error when using Tableau Output(v1.4): NoneType Object has no data attribute

[cro159]

I have recently upgraded by designer to 2023.2 to coincide with an Alteryx server upgrade.  My workflow was using an output to tableau server tool that no longer exists with the new version of designer.  I downloaded Tableau Tools v1.4 and set up a connection to the desired tableau server.

When I run the workflow in designer I get the following error in the Tableau Output: <class 'AttributeError'>: 'NoneType' object has no attribute 'dtypes'

Has anyone had the same error and how did you fix it?

I also solved this by parsing my Dateime inputs using the Date Time Parse tool, converting them to strings, and then back to the Date type using a Select tool.

Did you ever get a solution to problem 1?  I'm getting that issue when trying to run a workflow on the gallery.

Could you be more specific? I'm not sure what you mean by problem 1.
