Error in creating custom site definition in sharepoint 2016

I am creating a custom site definition which I'll be using as a site template. I am able to create one with a list and some message on home page. I created one visual web part and added in default.aspx by registering it on default.aspx page.

<%@ Register Tagprefix="MyWebPartControls" Namespace="CustomSiteDefinition.LogonWebPart" Assembly="$SharePoint.Project.AssemblyFullName$" %> 
<MyWebPartControls:LogonWebPart runat="server" />

It is giving result as expected.

Now I want to add some default web parts like "Document Library" on home page.

I am trying to edit in onet.xml.

As soon as I add above code I am getting following Error.

Find below stack trace.

Even if I try to add some custom web-part , I get these errors.

Any solution will be helpful :)
