Is there a way to use dot filter notation in the include spec of a DFE?
I am trying something like this but it is not working.
@DFE(interval='Day', period='DAY', metric='Quantity', flattenWindows = true, includeSpec='itemHistory.(exists(quantity)).quantity, itemHistory.(exists(quantity)).date') type ItemQuantityDFE mixes TSDataFlowEvent<MySourceType>
I get an error like this:
Unable to pre-fetch 1 source objects for type MySourceType; Filtering on fields with an included reference type not supported: quantity
Is there a correct way of doing it?
