Hello Everyone,
I'm trying to load the sage pay screen to confirm the order using plugin and this plugin calling the web API. When I'm trying to load sage pay screen by clicking the button I'm getting an alert with error message and also getting blank sage pay screen.
An unexpected error occurred from ISV code. (ErrorType = ClientError) Unexpected exception from plug-in (Execute): decm.Plugins.LoadSagepaytoConfirmOrder: System.Net.WebException: The remote server returned an error: (500) Internal Server Error.
Kindly have a look below screen shot
