I keep getting the following error:

  • Error executing background job, “Testing Database Connection” java.lang.NullPointerException at index 3 

I am running RapidMiner Studio 7.4.000

Can someone please help me fix this issue? I don't know how to alter custom drivers, so the more detail you can give the better.

    Does it require multiple classes? I know that Teradata needed that it drove me nuts to get it to work right.

     

    When you check the Database drivers, do you get a green check mark?
