I've been trying to hand off some content for our developers to test with. However, when they use the installation wizard to install my package, the installation fails. I checked their logs and am seeing this message:
ManagedPoolThread #12 16:16:04 ERROR One or more exceptions occurred while processing the subscribers to the 'packageinstall:items:ended' event.
Exception[1]: System.NullReferenceException

I found another post on here that would seem to indicate there's a missing item in my package that's causing the Solr index re-population to fail, but I don't know what it is. I've checked the package project over and over, I believe I've included everything. How can I find out what item is missing?
FYI, we all have Sitecore 9.1 with SXA 1.8 installed. The content is SXA based content.
