Publish to Tableau Server -Internal error: Upstream tool called push record in update mode

[fed_]

Hi everyone, 
I'm trying to push some data on Tableau Server, after manipulating it with Python tool. When run on my local machine everything works smoothly, however as soon as I try to save this very basic workflow to my company Gallery, I get the error below (see screenshot in attachment)
TableauServer.OutputDataConditionally - Internal error: Upstream tool called push record in update mode

Tableau tool works fine in other workflows and if I disable the container that includes it, I'm able to save/run/schedule on the gallery without any issue, so I guess it's coming from the combo Python+Tableau. I did some research, but I couldn't find any answer in the community...Any thoughts?

Cheers!

Hello @fed_ 
Thank you for reaching out!
Can you please post a copy of your workflow to your reply?

The error is referring to a specific tool (#44) and it will help to see what that tool is doing.

Thanks!

Hi @TrevorS , 
thank you for your reply!

I can only post a modified version of the workflow and without my credentials embedded in the python tool and Tableau tool. 
The original workflow consists only of the 4 tools in the screenshot:

• Python (1) : Pulls data using Request module, manipulates the json to populate the dataframe
• Browse (8) 
• Select (10) : Rename fields
• Publish to Tableau Server (9) : Publish data to Tableau Server as a .hyper file 

As you can see from the screenshot, the error primarily comes from Tool 9 (Publish to Tableau Server) when I try to save the workflow to my company's Gallery. However such tool works perfectly in all other workflows we have on the Server.
