Hi,
I am trying to pass custom object as a input parameter to function handler in c#. It is working fine locally. I have created the api gateway in aws lambda function. and trying to call that api through postman. I am passing custom object input parameter in body and returning the same object. but input is passing as null to the function handler.

public Rootobject FunctionHandler(EmailData input, ILambdaContext context)
{
var data = JsonConvert.SerializeObject(input);
Rootobject rootobject = new Rootobject()
{
isBase64Encoded = false,
statusCode = 200,
body = data
};
return rootobject;
}

public class EmailData
{
public string EmailAddress { get; set; }
public List<KeyValuePair<string, string>> files { get; set; }

}
 This is my code. Can anyone tell me what is the issue. 
Do I need to configure anything in api gateway to pass the custom object parameter?

Please help me.
