@vadlamudibi ,

If you downloaded Power BI Desktop from the Microsoft Store, you might be unable to connect to Oracle databases because of an Oracle driver issue. If you encounter this issue, the error message returned is "Object reference not set". To address the issue, do one of the following:

• Download Power BI Desktop from https://powerbi.microsoft.com/desktop instead.

• If you want to use the version from the Microsoft Store: on your local computer, copy oraons.dll from 12.X.X\client_X into 12.X.X\client_X\bin. The X represents version and directory numbers.
