If SharePoint on-premises, what's exact CU version: 16.0.4639.1002

Expected or Desired Behavior

I'm trying to create a site provisioning engine that generate a template on the fly. One of the tasks is to get the web parts on the homepage of the template site, extract them and add it to the template file. But the code failed on extracting the webparts. It' say:

Observed Behavior

What i expected is that the template file contains the part of the pnp:Page and have the web parts included in the template so if we apply it the homepage is the same as these from the template file.

Steps to Reproduce

• Install CSOM packaged from nuget
• Extract the template from one site in C#
• Make sure that you have the following code into your solution.
  ptci.HandlersToProcess = Handlers.Fields | Handlers.ContentTypes | Handlers.Lists | Handlers.Navigation | Handlers.PageContents | Handlers.ComposedLook;

Run the code and you will see that the Pagecontents is not executed or thrown an execption.

Exception:

Specified argument was out of the range of valid values.
Parameter name: controlId

Sometimes we get also this error message:

Field or property "ListId" does not exist.

Could you give some advice to have a workaround?
Thanks in advance.
