visual studio export template error 'invalid parameter'

Question

I'm using Visual Studio 2012 Premium on a 64-bit window's 7 laptop. I want to export a template but I get the following error when I click finish in the export template form:

Template export failed for the following reason: Invalid parameter  
Parameter name: index

To make it I start a project from an existing template (typescript nodejs; blank express application) and then change it up to how I need it. I do delete some folders and create new ones. I also rename the startup file from app.ts to server.ts. I can't find anything explaining this error, and http://msdn.microsoft.com doesn't have anything, as far as I could see. If someone could share some insight into how this problem or how to properly export a template it would be appreciated!

Same issue in VS2013. I created a new node.js console app and simply tried to export it as a template with same message. – Beckmann

I just ran into the same problem on VS2017. :( – Nimesh

Same issue in VS2019 as well, if someone could bounty this question that'd be nice... – Jacktar
