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

Start at the Get-PnPSiteTemplate provisioning-engine entry point and reproduce the command against the reported site or equivalent input. Trace the JSON conversion failure at $.position.sectionIndex, then identify the responsible source location and add a regression test showing the command completes with that data.
