Same behavior here too

[hittle08]

Same behavior here too, any updates on this?

[Leif-Frederiksen]

I see the same problem. 3.22.2006.0 worked for me but not 3.25.2009.1

[hittle08]

Who at microsoft do I need to contact about this? I have a premium subscription with them and I keep getting bounced around between the SharePoint team, Azure Team, and Office 365 team.

[NicolasKheirallah]

PnP is a community project,I recommend you downgrade to 3.22.2006 for now

At 3.22.2006 my provisioning template is not set correctly. It works locally at 3.24 and 23.25 - but these versions won't go on Azure. Does anybody know if there's going to be an update soon?

[Rob3r70]

Last one I was able to run in Azure is: 3.23.2007.0

I just tried this for the first time today and got the same error...I am running 3.26.2010.0. Is there any fix other than running a lower version of PnP?
