iOS: taskConfig is randomly nil

Is this a bug report, a feature request, or a question?

Bug Report

Have you followed the required steps before opening a bug report?

[x] I have reviewed the documentation in its entirety, including the dedicated documentations :books:.
[x] I have searched for existing issues and made sure that the problem hasn't already been reported.
[x] I am using the latest plugin version.

Is the bug specific to iOS or Android? Or can it be reproduced on both platforms?

iOS 17.4.1 (physical device) (I haven't tested it on Android yet, but I will update this issue if I experience it on Android.)

Is the bug related to the native implementation? (NSURLSession on iOS and Fetch on Android)

I'm unsure but I believe it's native RNBGD code.

Environment

Environment:

  react:
    installed: 18.2.0
    wanted: 18.2.0
  react-native:
    installed: 0.73.5
    wanted: 0.73.5

"@kesha-antonov/react-native-background-downloader": "^3.1.2"

Expected Behavior

When a task finishes downloading, taskConfig should not be nil.

Actual Behavior

Randomly, all download tasks have a nil taskConfig. See here for reference

I discovered this because my downloads randomly aren't progressing (no downloadProgress event). To identify this, I added some additional debugging and checked the logs, and confirmed

Steps to Reproduce

I'm honestly not sure. I haven't been able to identify reproducible steps. I don't know if MMKV isn't persisting correctly or if there is some other issue.

If I'm able to identify reproducible steps I'll update here.

When this happens, closing & relaunching the app typically fixes the problem.
