react-native-camera video capturing shows error on preview after it gets captured?

Question

I am using react-native-camera for video capture. I am building something kind of snapchat stories where moment you capture video next to that it takes you to the preview screen of video where you can edit. On press of start button while videoCapturing screen it returns path of the video but on press of stop button it returns an error at the same time making video to get stored to my device storgae. I have posted both videocapturing screen as well error I am getting on press of stop button.Attached code for the VideoCapture screen.
