Invalid_request_error Validation error: Expected object, received array

Hi,

I keep getting an error when I try to pass a JSON file from Aggregate to JSON module to Dust - Make an API call module

I suppose that Dust module needs to receive a JSON object but I cannot figure how to prevent Aggregate to JSON module to put brackets. I’ve tried to set a Create JSOn module just after Aggregate to JSON but without success.

Below some screenshots of my setup. Any help would be greatly appreciated!!
