Startup.cs Error (line 90) when publishing to production server.

I'm getting an error in Startup.cs (line 90) when publishing the website to a production server and trying to get it running.

It's a null reference error showing this to be null...

var applicationUrl = Configuration["ApplicationUrl"].TrimEnd('/');

Any reason why this is occurring? I haven't had any trouble with previous .net core versions using your startup template.

Hi,

look into the appsettings.json if there the entry:

"ApplicationUrl": "http://localhost:5000",
