The JSON value could not be converted to System.Int32.

Hello,

I'm having the following issue when trying to run the following command over an specific site:

Get-PnPSiteTemplate -Connection $connection -Out $output -Encoding ([System.Text.Encoding]::UTF8) -IncludeAllPages -IncludeAllTermGroups -IncludeNativePublishingFiles -IncludeSearchConfiguration -PersistBrandingFiles -PersistPublishingFiles -Force

Everything goes normal until I get this error in debug output:
Extracting Template from https://n36j.sharepoint.com/sites/S… [Client Side Page Contents ] 81167717-0a13-41cc-9b59-8cd7924a2669

This is happening using PnP.Powershell in latest version (1.11.0), but also in the most recent nightly (1.11.124-nightly). I'm opening the issue here as it's what they suggest in their git repo:
...

1. Are you using Invoke-PnPSiteTemplate or Get-PnPSiteTemplate? The issue is most likely related to the Provisioning Engine. The Provisioning engine is not located in the PowerShell repo. Please report the issue here: https://github.com/pnp/pnpframework/issues.
   ...

How could I investigate further this problem?

Thanks for any help.
Best regards,
Jorge

Hello @jansenbe and @pkbullock,
I noticed the same error. It seems to be a problem with the PagesContents Handler and the Image WebPart. These are the steps to reproduce it.

• Create a communication site
• Apply the site template "Leadership connection"
• Run the PowerShell command or CSOM command below
• It will fail for the page "Contoso-Leadership.aspx" with the error The JSON value could not be converted to System.Int32
• By removing the image WebPart the "Contoso-Leadership.aspx" is properly exported

Get-PnPSiteTemplate .\template.pnp -Handlers Pages,PageContents -IncludeAllClientSidePages -PersistBrandingFiles -Debug

ProvisioningTemplateCreationInformation creationInformation = new ProvisioningTemplateCreationInformation(context.Web);
creationInformation.PersistPublishingFiles = true;
creationInformation.IncludeAllClientSidePages = true;
creationInformation.HandlersToProcess = handlers;
context.Web.GetProvisioningTemplate(creationInformation);

Cheers

Any news about this problem?

I think this is resolved on the PnP.Core in version 1.9, just update the references to this version

pnp/pnpcore#1058

I updated my PnP.Framework and resolved the issue
pnp/pnpcore#1180
