Install an app using PowerShell Script.

Question

Hi,

 

I have a SPFx package Hello-World.SPPKG. I have to deploy to Apps and then add(install) the app to the SharePoint Site(2016) using a powershell script. I get this error,

 

Install-SPApp : Value cannot be null.

Parameter name: xeAppPermissionRequests

 

Any help would be useful. Thank you.
