Network failures resulting in unhandled exceptions

This may be due to changes in React Native 0.55, I’m not sure. Our crash analysis tool is reporting these unhandled exceptions for a plain GET when the network connectivity is bad.

node_modules/react-native/node_modules/whatwg-fetch/fetch.js in listener at line 440:21

        options.url = 'responseURL' in xhr ? xhr.responseURL : options.headers.get('X-Request-URL')
        var body = 'response' in xhr ? xhr.response : xhr.responseText
        resolve(new Response(body, options))
      }
      xhr.onerror = function() {
        reject(new TypeError('Network request failed'))
      }

The events leading up to it:

xhr GET https://my.api/someparam [0]

sentry TypeError: Network request failed

exception TypeError: Network request failed

I saw this once in the debugger but forgot to capture the call & response.

Yes, sorry wasn’t clear about that. There’s a wrapper class that creates the apisauce instance and assigns it to the request key.

All good! Thanks for the follow up!
