Invoke-PnPTenantTemplate appears to timeout after 30 min. with DeviceLogin

I'm on v1.8 and try to apply a somewhat large tenant template that creates 15 com. sites, and applies 4 different site templates across the sites. It's basically 3 hubs with 3 associated sites and 3 single sites. I have tested each hub part and single sites of the template, for example just deploy 1 hub site and 3 associated site and apply their associated site template. All parts of the template work when tested isolated.

But when I run everything as one big template it consistently fails after about 30 min. By this time all sites have been created and 1 or 2 site templates have been applied. The error I get is "A value cannot be null", Parametername: clientObject.

Minutes before invoking the tenant template I have authenticated with Connect-PnPOnline <> -DeviceLogin -LaunchBrowser.

Could this be a timeout issue? Unfortunately Set-PnPTraceLog does nothing so it's not easy to get more specific on the error.

Thanks.

It would seem that threshold is different on dev tenants as opposed to "regular" tenants. I tried 3 different Dev Tenants and all saw the same issue. Provisioning would suddenly halt, and from time to time simply just "timeout" with TaskJobCanceled og 404 - Not Found.

Once I tried a production tenant everything went smooth without any issues.

Can anyone confirm this?
