iOS Native Crash when uploading blobs using aws-sdk

[chris-feist]

When using the aws-sdk package on iOS to upload files to S3, iOS experiences a native crash. I have narrowed it down to this line here: https://github.com/facebook/react-native/blob/v0.61.5/Libraries/Blob/RCTBlobManager.mm#L101. If I comment out that line, then the upload works fine. I am not an iOS expert, so I am not sure what it is doing. Maybe the original author can comment: @satya164

React Native version: 0.61.5

Steps To Reproduce

1. I have created an Expo snack with a repro case: https://snack.expo.io/@chris-feist/document-upload-issue-demo
2. Select file and upload it using the aws-sdk and S3 client.
3. Note that it does not repro when the device/emulator is connected to the RN debugger

Describe what you expected to happen:
I expect the upload to work (as it does on android).

I am experiencing the same problem on IOS with the aws-sdk ( "aws-amplify": "^2.2.7",)/ after installing react native 0.61.5 on a physical device with Testflight. Same code works fine with RN 0.61.4. The crash happens randomly after every one or two PUT uploads. I have also tested with commenting out the suggested line: https://github.com/facebook/react-native/blob/v0.61.5/Libraries/Blob/RCTBlobManager.mm#L101. But i my case the crash still occurs randomly after a couple of PUT uploads. Same code on Android works fine.

[thekrol01]

Any workarounds?

[chris-feist]

Any workarounds?

Yes, in your node_modules comment out the 3 lines here

//  if (offset != 0 || (size != -1 && size != data.length)) {
//    data = [data subdataWithRange:NSMakeRange(offset, size)];
//  }

Then use something like patch-package

Edit: Looks like you said you tried that. I have been using this workaround for 2 months without issues

[thekrol01]

Thank you for the reply. Perhaps I am doing something wrong. I only commented out the lines in node_modules. Do I have to patch the module to make it work? Perhaps you have more details on how to do this?
Did you also clean cache etc in Xcode before you ran a new build?
