"Cannot read property _location of null" when testing with Jest and react-testing-library

Hi,

I am encountering this issue intermittently but regularly when testing my NextJS React application using Jest and react-testing-library:

"Cannot read property _location of null"

This happens, I believe, because the Jest test process exits too quickly relative to what Apollo is doing, but I confess my understanding of this is a bit lacking.

I would appreciate any guidance on the issue and how I can resolve it! I can provide examples of my test setup if it would help.

Thank you

Hi @boileroo :wave: I don’t know enough to say what the issue might be, but your comment:

Makes me wonder if you have some unresolved promises that you’re not awaiting in your test suite. Hope that helps!
