Hi,
I'm working on MacOS. I have several several scheduled flows that have been running daily for several months, which source data from Amazon Athena and Databricks. On 03/06/2026, these scheduled runs failed, and the following error message was displayed:
- "Error reading flow file. Open the flow file in Tableau Prep Web Authoring or Tableau Prep Builder and then try to republish it to your server."
If I try to edit the flow on the browser version of Tableau Cloud, the page never fully loads. If I download the flow and use the desktop version of Tableau Prep Builder (version 2026.1.2), I can open the flow and check that there are no errors, but when I try to publish it, I get the following error message:
- "Error publishing flow to Tableau Server."
Any advice would be greatly appreciated.
Thanks.

Do you mind to try with Tableau Prep Builder 2026.1.0:
https://www.tableau.com/support/releases/prep/2026.1It seems Tableau Cloud Prep has been updated to 2026.2.0 (This Tableau Prep Builder version has not been released):
Thus, if you can't open the flow, mostly this can be related to the update.
If you are not able to edit the flow (browser of 2026.1.0 release) then I recommend you to create a support case:
