Hello, I was trying
CloudDeploy[
FormFunction[{"message" -> "String"},
FindTextualAnswer[#message, "How many hours do I sleep?",
1, {"String", "Probability"}] & , "PNG",
AppearanceRules -> <|"Title" -> "Describe how is your sleep."|>],
Permissions -> "Public"]
but it returns $Failed after evaluating the API in the input "My sleep is fine. I sleep 4 hours per night.". How could this error be fixed?
