I configured Data Action with Input and output contract, I get back raw output in JSON When I test action and when I call Data Action in Architect Flow I get all Input and output fields, However I am unable to playback output in Audio prompt.
So I get Balance due as 7656 for example but I cannot playback to customer.
Click the Play button next to the "Your Balance is" field which will open Audio sequence builder. There you will need to use Data option, select the Balance output variable and choose how you want value to be played
Did you make sure that the data from the CRM gets correctly populated during execution of the flow? Have you tried saving that data in different slot type (Number, String, ...) ?
Can you show the interaction logs/details of your testings?
