Fetch generic error message

[Swackles]

Introduction

For the past few days, we've been debugging an issue with our API calls, and this issue was made harder by the generic "TypeError: network request failed" message, which didn't give us much info to go off. I ended up making our own simple fetch to see what the actual error message was and from there it was very simple to debug the issue.

Details

Maybe there's a way to get better error messages from a fetch that I don't know of, but if there isn't I'd like to discuss change so that error message from the native side gets passed back to react.

Discussion points

• Is there a better way than already exists?
• Why does fetch currently return a generic error message?
• What would it take to change it?
