Two weeks ago, my Tableau Prep desktop connected to Salesforce successfully. Yesterday, I got the following error message:
"Can’t connect to Salesforce
Detailed Error Message
TableauException: An unknown error related to remote content was detected (500)
UNSUPPORTED_API_VERSION: Invalid Api version specified on URL"
I was using 2025.1.1 for months. Yesterday, I upgraded to 2025.2.3. The upgrade didn't fix it.
Thank you in advance for your help! I don't know where to start...
Hi everyone,
I ran into the same issue with Tableau Desktop and managed to work around it by manually changing the Salesforce API version. However, it seems the solution doesn’t apply to Tableau Prep.
In my case, I was using a template workbook from Tableau Exchange. I downloaded the .twbx file, renamed it to .zip, and extracted it to access the .twb file. Since the .twb is editable, I opened it with a text editor, found the Salesforce API version (which was set to 25.0), and updated it to 31.0 because Salesforce recently deprecated API versions below 31.0. After saving the .twb, I opened it directly in Tableau Desktop, and the data source refreshed without issues.
I tried doing the same with a .tfl file for Tableau Prep. I could open it in a text editor and locate the API version, but after modifying it, Tableau Prep was no longer able to open the file.
