Facing issues in displaying API response in Carousel

I want to display API response data in custom Carousel card for my bot and I am facing issues in doing so.
The API I am using: POST:
In Post-man, under Body: form-data:

hmac:dev-hmac
hmac_signature:22681789c90efa128877d8fc719fa7a4daad49f968aab64890662dc92eea4c6b
nlu_payload:[{“entity”:“orderBy”,“value”:{“value”:""}},{“entity”:“intent”,“value”:{“value”:“movieSearch”}},{“entity”:“movie_name”,“value”:{“value”:“Jumanji”}},{“entity”:“person_name”,“value”:{“value”:""}}]
intent:movieSearch
query:Suits
uid:1234567890

the important variable that I am passing is ‘nlu_payload’ and ‘intent’ rest are default values

It should look like this:
