I have a project that works locally, on our dev server, and on our production server.
When I try to run it on the test server, I get the error below, and I don't know what to do about it beyond stare at my screen blankly. Hints? Process to trace the issue to its source?
I've installed the NuGet package for Oracle 12.2, etc.
Could not load type 'OracleInternal.Common.ConfigBaseClass' from

The Web.Config has the following blocks in it:

</connectionStrings>
NOTE: There are other projects working on this server, they're just using a different version of the Oracle client for .Net. None of the others is using only the Managed driver. I am looking for a way to dig into this error, some hint as to where that type is sourced and loaded from.
