https fetch throws exception on move from foreground to background and then back to foreground

Expo SDK
1

Please provide the following:

  1. SDK Version: 35
  2. Platforms(Android/iOS/web/all): iOS

My app makes networking fetch calls that can take 5-10 seconds to return sometimes. If the user puts the app into the background and then later puts the app state to active, the fetch call throws an exception.

I don’t need to have the https fetch call actually process in the background, but is there a way for it to complete successfully once the app returns to the foreground (active) state?

Hey @todaq,

Are you using the BackgroundFetch module and this is occurring? Or are you just performing standard fetch calls?

Cheers,
Adam

standard fetch calls. I don’t need it to process in the background, I just need it to complete when the user brings the app back to the foreground. Do you have to use BackgroundFetch in this case?
