CRITICAL - Uncaught TypeError: Cannot read property 'path' of null on video select

[andrewm-mitchells]

Describe the bug
When selecting a video the app crashes with the error listed in the title. It seems to work on iOS 15 beta but crashes on 14.5 at least in simulator for me but couple of internal testers reported it crashed on them when used on an actual device.

To Reproduce
Install the plugin, follow instructions in the plugin documentation, attempt to add a video when running test app in simulator.

Expected behavior
Video selected with no errors and uploading process starts.

It seems like the issue is isolated only to iCloud stored files. While it's crossed on the plugin docs page it doesn't seem to be working properly in the current version or I'm doing something wrong.

In iOS after selecting file you may not be able to use it directly. In this case you will need to copy that file in your app directory.

Looks like the plugin is deprecated and development on it is dead unfortunately. Going to be looking for alternatives.
