Specified network layer is invalid : SQLite when using Bussiness object SL Java SDK

[ansanes]

Getting an exception when using the bussiness objects SL java sdk to retrieve information about a universe.

this is my code:

 String blxPath = cmsService.retrieveUniverse(universePath, tempFolder, true);
      System.out.println("Loading universe" + blxPath);
      RelationalBusinessLayer businessLayer = (RelationalBusinessLayer) localResourceService.load(blxPath);

The issue lies in the fact that you're trying to work with a universe that uses a connection type no longer supported by the SDK—specifically, SQLite.

Try opening a different universe that connects to a supported database (such as Oracle, ....) and see if the error persists.

Hope this helps!
