Method onError() called with error 'null', when i use the pickContent() to pick image or video !!!

[DilbagSandhu]

My device is redmi Note 4 running 7.0
I am calling the contentManager inside SupportFragment

1. onActivityResult() returns the image data
2. then onStartContentLoading called
3. then onError with null parameter called and nothing gets loaded

this library worked for first two days, now it is loading nothing
