Install update error, desktop updates correctly

Hi Syndicate_Admin,

Thank you for reaching out to the Microsoft Fabric Forum Community.

The recent update to the 64-bit Oracle Client 19c (version 19.27) is likely the cause of the increasing column-related errors during scheduled refreshes in Power BI Service. The newer driver may handle metadata exposure differently, causing the gateway to fail to detect certain columns that Power BI Desktop still recognizes due to cached data. Since the gateway relies on the Oracle client for data access, any issues with the driver can directly impact refresh functionality. To resolve this, you can either roll back to the previous Oracle client version that worked reliably or try reinstalling the current version to fix any configuration issues.

If the issue still persists, I’d recommend raising a support ticket with Microsoft. The support team can look into the backend and provide more in-depth assistance tailored to your environment.
