Receiving error telling me power BI needs Oracle client software version 8.1.7 or greater. Have much

[Anonymous]

The error message is

DataSource.Error: The provider being used is deprecated: 'System.Data.OracleClient requires Oracle client software version 8.1.7 or greater.'. Please visit https://go.microsoft.com/fwlink/p/?LinkID=272376 to install the official provider.

I'm not sure what to do, given that I had version 19.something already. IT tried installing the oldest version they could, version 12.1.0.1.2. But that didn't work either.

Thanks for your help.
