Get-PnPTenantSite : System.InvalidOperationException: The type of data at position 1684 is different than the one expected.

[siata13]

Hi,

When try to obtain the PnPTenantSite information exception is thrown. Seems, it is related to parsing of the JSON result received from O365. I have checked the traffic with fiddler and it seems that the result coming from O365 is correct.

This seems related to the PnP Core PowerShell component... best to submit this question to that specific repo's issue list: https://github.com/SharePoint/PnP-Sites-Core

It is not related to PnP Core Powershell. The exception is coming from Microsoft.SharePoint.Client.JsonReader.ReadGuid().

Please reopen.

The issue is in the underlying CSOM APIs or specifically in the server side APIs and is being worked on. Path deployment should get on hold and canceled so we should not have new tenants experiencing this anymore. The fix is being worked on and it will be shipped server side as soon as possible, but can't provide an exact ETA at this point.

Thanks for reporting this.
