Cannot read property 'pageLoader' of null

See original GitHub issue

Bug report

Hey guys, I saw this issue #9951 being resolved, but I am having the same error with react-testing library

Describe the bug

I am trying to test a component, but have “Cannot read property ‘pageLoader’ of null” all over my tests (actually as many of them as many Links I have on a tested page)

I am using NextJs with Redux example and test it with react-testing-library.

the error:

[Error: Uncaught [TypeError: Cannot read property 'pageLoader' of null]
