Get-PnPSiteTemplate with -PersistBrandingFiles switch leads to "File Not Found"

Hi,
I could narrow down the issue I am facing. When generating the Site Template, it all works until I use the PersistBrandingFiles flag.
In this case, the following errors are traced whereas the last one is repeated a lot of times until the script stops eventually.

I have tried both, authentication with app only (certificate) and interactive with no difference.

1.10.0 PnP.PowerShell

Get-PnPSiteTemplate -Out $templatefileName -Connection $sourceConnection -PersistPublishingFiles -IncludeAllPages -IncludeSiteGroups -IncludeNativePublishingFiles -PersistBrandingFiles -Force

Get-PnPSiteTemplate: File Not Found.

It results in not generating the template file.

Start at the Get-PnPSiteTemplate handling of -PersistBrandingFiles and the automatic client side page connected file export described in the report. Reproduce the command shown, then trace the ServerRelativeUrl error and repeated File Not Found responses. Done means the template is generated without those errors.
