Error on Append - Publish to Tableau Server

Hi...

I have a workflow that needs to append weekly to the data source in Tableau Server. I'm getting the following error

I can create a new data source by running the workflow on desktop, but I can not append it.

Alteryx Desktop: 2019.3.2

Tableau Server: 2019.2.2

Publish to server Macro: 1.08.1 (?)

Any help is appreciated.

@Watsa had a similar if not exactly the same issue earlier this year. Have a look at the link below:

I am wondering if you do this, if it resolves your issue?

The differences is we haven't updated the Tableau Server and I couldn't manually append either.
