Provider.GetTemplate() returns Unable to load one or more of the requested types. WHEN together with Graph SDK 5

[mmsharepoint]

Vers: 1.16.0 \ 1.16.1-nightly
Steps to reproduce:

• Create console app
• Add Microsoft.Graph(.Beta)
• Add PnP.Framework
• Add simple PnP template (to project root for simplicity)
• Add 3 lines of code
  string path = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
  XMLTemplateProvider provider1 = new XMLFileSystemTemplateProvider(path, "");
  var template1 = provider1.GetTemplate("TemplateBasic.xml");
• Fail at line 3 with

Just upgraded from .net 6 to 8 and updated MS Graph SDK from v3.33.0 and Pnp Framework version 1.16.0 to the latest MS Graph SDK v5.56.0 (Pnp version remained at v1.16.0) and we are encountering almost the exact same error message while either saving XML file using the below two lines,

XMLTemplateProvider provider = new XMLFileSystemTemplateProvider(directoryPath, "");
provider.SaveAs(template, "template.xml");

OR if we do not save the xml file to get around the initial error, while applying the template.

web.ApplyProvisioningTemplate(template, ptai);

Error below:

I encounter the same errors like mmsharepoint. I am using .NET 8 / pnp.Framework 1.16.0 / Microsoft.Graph 5.56.0 / Microsoft.Graph.Core 3.1.15.

Failing on second line:

var provider = new XMLSharePointTemplateProvider(csomContext,
"https://contoso.sharepoint.com/sites/site", "Templates");
var template = provider.GetTemplate("template.xml");

@mmsharepoint Did you find a workaround?

[MathieuMarchant]

Same issue here, was anybody already able to resolve this?

[brnowakowski]

Any progress on this?
