Hello,

I'm working to deploy from sandbox to our production environment.

When I validate the inbound changeset in our production environment, I get the following error:

System.NullPointerException: Attempt to de-reference a null object
Stack Trace: Class.MassUpdateSimpleControllerTest.testOpportunityInRelatedList: line 148, column 1

line 148 reads:         System.assert(controller.getFieldTypeOptions().size()>1);

I've done some research and have seen you can possibly comment-out the line in question, or de-reference the null so that I guess a new object is created and the code works properly (I'm not quite sure I understand this one) I've tried to edit this code to make it work, but still have errors. Can anyone help me, please?!

I have very limited coding and Salesforce experience, so any clarity and insight is appreciated!

Here is the Apex Class Code:

I have a custom tab for a custom object that is used regularly in our org. We are making the switch to Lightning, but I cannot get this one tab to show up in Lightning. It is available in classic and I can access it from the waffle icon in Lightning. Below are some screen caps of me adding it to our Lightning navigation menu. I've set everything else up the same way and it is working fine. Any thoughts on what I could be missing?
