ColdFusion - Vonage Inboud voice api call Answer Webhook CURL - issue with ncco object can't send multiple response to text to speech

Question

I am successfully able to recive inboud call on my webhook and it works nicely i got the automated voice of below text it is working good. however i am getting "Unexpected content type: text/html; charset=UTF-8" on events.

<cfset ncco = '
{
        "action": "talk",
        "text": "Press 1, for maybe, and 2, for not sure, followed by the hash key.",
        "language": "en-US",
        "style": 6,
        "bargeIn": true
}'>
<cfhttp method="PUT" url="https://api.nexmo.com/v1/calls/#responsetxt.uuid#/talk" result="httpResponse">
        <cfhttpparam type="header" name="Content-Type" value="application/json" />
        <cfhttpparam type="header" name="Authorization" value="Bearer #jwtToken#" />        
        <cfhttpparam type="body" value='#ncco#' />
</cfhttp>

when I got inboud and pass the following ncco it doesnt work and call disconnected. but this works good with outbound call voice recorded and transcripted.

<cfset ncco = [
        {
            "action": "record",
            "eventUrl": ["https://example.com/virrtualcall/input.cfm"],
            "transcription":
            {
                    "eventMethod": "POST",
                    "eventUrl":["https://example.com.com/virrtualcall/input.cfm"],
                    "language": "en-US",
                    "sentimentAnalysis": "true"
            }
        },          
        {
                "action": "talk",
                "text": "Please let us know what is your problem",
                "language": "en-US",
                "style": 6,
                "premium": true,
                "bargeIn": true
        },
        {
                "action": "input",
                "type": [
                        "dtmf"
                ],
                "dtmf": {
                        "submitOnHash": true,
                        "timeOut": 10
                }
        },
        {
                "action": "talk",
                "text": "Thanks for your response, goodbye.",
