Office 365. Cannot Convert Object Problem when provisioning pnp:File Display Template | José Quinto

Introduction

When we are using PnP Provisioning Core Engine to deploy SharePoint artifacts, we probably need to deploy Display Templates.

My colleague Kevin posted this blog post about this: http://sharepointcookies.com/2015/07/working-with-display-templates-with-the-new-pnp-provisioning-core-engine/.

Problem

But, some changes has been done in the PnP Provisioning Code and we need to adjust a little bit the code.

I am using PnP Version (v2.4.1605):

 

Here is the error received when I tried to provision Display Templates:

Cannot convert object of type 'System.Int32' to type 'System.String[]'

Solution

Note that the problem where two properties: UIVersion and TargetControlType and the workaround was to wrap them into string array.
