When creating or updating content types using PnP/CSOM we are encountering the following error upon executing the query:
Microsoft.SharePoint.Client.ServerException: Value cannot be null. Parameter name: s
The routine had been working for months up until the past couple of days, and only seems to affect a few tenants, works fine for most others.
The content type in question is a relatively simple content type.
Has anyone else come up against this error? Or has any workaround?
