(Batch)HttpLink Uncaught (in promise)DOMException: signal is aborted without reason about apollo-client HOT 6 CLOSED

I'm close to get a minimal repro. Manage to at least setup http link in code sandbox at least, but it's not reproing in my setup yet
I'll try again a little later, not 100% sure what else I have on my real setup that might affect this
See current setup here
Navigating quickly between Home and Home2 causes to cancel the request, but no repro yet

Glad you found the source of the issue! Appreciate you letting us know! Have a great rest of your day 🙂

Hey @Cellule 👋

Thanks for the report! By chance do you see the same thing with HttpLink, or just BatchHttpLink? FWIW we do the same thing in HttpLink here:

If you're not seeing this issue in HttpLink, I think that gives us a place to start.

I just tested and indeed same behavior with HttpLink.

Alright, we finally managed to find the problem.
Turns out it has nothing to do with HttpLink.
We had some custom fetch response handling that was now getting a rejection from the fetch abort

I have updated the repro above showing the issue.

In essence we had code looking like this

const httpLink = new HttpLink({
  uri: `/graphql`,
  fetch: (...args) => {
    const res = fetch(...args);
    res.then(
      (value) => {
        // inspect response headers to update application state
      },
      // This was missing, so the rejection from fetch was unhandled in this .then()
      // Causing to print the error
      // (err) => {/* Ignore fetch errors */}
    );
    return res;
  },
});
