Iterable Record Object

I am using a Pipeline to search for records
Get the value of a Formula Numeric Field
Sum and write that value in another record.

The error message I am getting is:

Validation error: Incorrect template "
{{b|sum(attribute='total_event_bom_item_sell_price')}}".
TypeError: 'Record' object is not iterable


I have successfully done this with other Formula Numeric Fields, so I am not sure why it would break for the same calculation somewhere else.

I did open a Support Case but I have got Boston a bit flummoxed.   

Any ideas?
