Unhandled Promise Rejection Warning

[ShwetaKhera]

I ran the command " cordova plugin add cordova-plugin-video-player " and gives me the following error:

(node:4008) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejec
tion id: 1): Error: cmd: Command failed with exit code ENOENT
(node:4008) [DEP0018] DeprecationWarning: Unhandled promise rejections are depre
cated. In the future, promise rejections that are not handled will terminate the
Node.js process with a non-zero exit code.

command " ionic info " shows :

Video player returns a promise, so you need to catch it.
async playVideo(){ try{ await this.videoPlayer.play(url); console.log("Video is complete"); } catch(e){ console.error(e); } }
This gets rid of the Unhandled promise rejections for me, hope this helps if you haven't solved it already.
