An unexpected error occurred from ISV code. (ErrorType = ClientError) Unexpected exception from plug-in (Execute):
System.ArgumentNullException: Value cannot be null. Parameter name: source
ColumnSet OQOcols = new ColumnSet(true);
Entity OQO = service.Retrieve(entity.LogicalName, entity.Id, OQOcols);
"opportunity", accurate guid, cols -- nothing is null
I have no idea what parameter "source" is. It worked last week.

weird
after more attempts the debugger got past that retrieve until I found the actual error: something.Where<Entity>(y => y.Id == product.Id); when something was null.
Sorry. Mystery solved.
