I am using a python script in Tableau prep, and this error keeps popping up:
System error: Failure loading FedOp: D:\tc\work\maestro-2021-2\g_pc\modules\platform\tabcore\main\parser\DataValueParser.cpp|`anonymous-namespace'::TupleParser::Parse|181 value - empty text
I found this article that I believe has the fixes for it. (https://kb.tableau.com/articles/Issue/tableau-prep-system-error-failure-loading-fedop) I don't want to update Tableau Prep, but it does have one fix that does not involve that. It says to:
Set environment variable useJaxbSerialization=true
How do I do this? In the environment variable screen, do I just write, "useJaxbSerialization=true" for the Variable value and "Tableau Prep bug fix" for the Variable name? Also, I am using a virtual environment to run Tabpy, and if that is responsible for the error, I am not sure how to set an environment variable in a virtual environment. I am using Tableau Prep 2021.2.3.
I assume they mean set the value in the System variables.
try:
useJaxbSerialization
and value true
