I'm building a flow based on Microsoft-Teams and Adaptive Cards.
One of the cards that I post haves a Input.Number, as the image:

But, when I trigger the flow, insert the data in and Submit the answers, the flow returns me this error:

I don't know why it's returning a Str if the input is "Input.Number" (lol). Am I missing steps, is there something more that I should do?
Thx in advance.
