React Native application crashes when opening from the background after unlocking the phone (network request failed.)

We have a problem with the React Native application that we are creating. The application behaves perfectly until the following happens:

  • the user locks the screen (while the application is open or in the background, it does not matter)
  • user opens iPhone and opens application from background state
  • as soon as the application makes an API request, it crashes

Some notes:

  • We create an application on the device itself (both miniature and non-minimized bundles create the same error).
  • If the user does not lock the screen (only puts the application in the background) and then opens the application later, it works fine.
  • Failure occurs in both Debug and Release schemas.

We checked the crashes in both Xcode and the Chrome React Debugger, and the following error occurred (not so useful). ( Note: This uses a debugging scheme).

{ [TypeError: Network request failed] line: 5074, column: 21, sourceURL: 'http://192.168.0.30:8081/index.ios.bundle?platform=ios&dev=true' }

The same error occurs when building using the release scheme.

Does anyone know what could be a potential problem here? Thanks in advance!
