Uncaught TypeError: Failed to fetch simulated offline in Google Chrome.

Intended outcome:

When making a query or polling query and the network has an outage/offline/disconnected. NetworkError is caught, retry-link retries. Polling queries would retry.

Actual outcome:

Uncaught TypeError: Failed to fetch.

Uncaught TypeError: Failed to fetch

When network connection comes back. No retry attempts are made, and no polling queries are retried everything just stops.

How to reproduce the issue:

Have a retry-link.

Make a query or polling query during a network outage. Can simulate network outage in Chrome Network tab under the throttling drop down. Restore network connection and see that nothing is retried.

@LiamKarlMitchell Hi! Thanks a ton for opening this issue. I’d need to take a bit of a deeper dive before I can confirm it’s related to #9870, as for the most part that issue relates to error reporting, rather than re-polling/fetching errors.

Is there a way I can have package.json switch over to using the git repo I clone from this project?

Yep! After cloning and building this repo, cd to /dist and run npm pack which will create a file named apollo-client-3.xx.tgz in the apollo-client/dist directory

Then in your app, run npm i ~/path/to/folder/apollo-client/dist/apollo-client-3.xx.tgz to install the newly built/modified client. You should see the package.json change to look something like this:

Still a concern, but I have not had the time to investigate it further yet.
