I'm trying to connect oracle database using prowerbi desktop. Throwing following error
Details: "An error happened while reading data from the provider: 'Object reference not set to an instance of an object.'"
Any idea why i see this error? I have searched it before posting here and found no clue.
Solved - The issue is because of the versions of Oracle client and Power BI desktop.
Oracle client was 32 bit and Powerbi was 64 bit, after updating oracle client to 64 bit everything works great.
