Dashboard with streaming dataset: Q&A card is blank

[mojoyoyo]

Hello, 

I've been trying to set up a Q&A card from a card that gets data from a streaming dataset. However, whichever question or visual I use, I only get a blank visualization (no data?). Does anyone have a solution to this problem?

Thanks!

I use the following schema on my streaming dataset:

And this is an example question I ask:

However, as I said, I get a "Blank" result regardless of what question I ask, even though I get data to the streaming dataset and can display it in a card of gauge, for instance.

can you give an example of a question you tried and provide the data you need in some sample data.  What measure is being used in the question, what code is used to create it if it is one that was created?
