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 👋 I don’t know enough to say what the issue might be, but your comment: > This happens, I believe, because the Jest test process exits too quickly relative to what Apollo is doing Makes me wonder if you have some unresolved promises that you’re not `await`ing in your test suite. Hope that helps!
