Experiencing YSODs when visiting some of the category pages, but only on the litium test-environment.
After restoring the production database to the test-environment (litium hosted) we started seeing YSODs cropping up when browsing the category page on the test-environment.
The error doesn’t crop up on prod so I figured I’d restore the test-db locally to trouble-shoot the problem but, as it turns out, the error doesn’t turn up locally either.
So the error is reproduceable on test-env but not on prod or locally.
Does anybody has an incling of what could make the category page fail on test but not on local or prod?
I have re-build and re-updated the search indices in case the search was the culprit but that doesn’t seem to help.
The error is:
[NullReferenceException: Object reference not set to an instance of an object.]

**Row 185:**
variants = variants
.Where(x => x.ChannelLinks.Any(z => z.ChannelSystemId == _requestModelAccessor.RequestModel.ChannelModel.Channel.SystemId))
.OrderBy(x => x.SortIndex);
As far as I know, no changes has been made to ProductSearchService.cs in the accelerator.
So what can make variants be null on row 185 on test-env but not locally and prod when using the same db?
