Welcome to the RingCentral Community

We are trying to use /ai/insights/v1/async/analyze-interaction endpoint described in Extract interaction analytics from a media file (ringcentral.com). We tried multiple options for `insights` field but none of them returned any Emotion insights.

In documentation there are emotion insights for each sentence in utteranceInsights

"utteranceInsights": [
    {
        "start": 2.52,
        "end": 6.53,
        "text": "Could produce large hail isolated tornadoes and heavy rain.",
        "confidence": 0.93,
        "speakerId": "1",
        "insights": [
            {
                "name": "Emotion",
                "value": "Neutral",
                "confidence": 0.7
            }
        ]
    }
],

but in our tests, regardless of what recording we send, the insights array is always empty.

Sample request:

1. With "all" insights:

{
    "contentUri": "file url",
    "encoding": "Mpeg",
    "languageCode": "en-US",
    "speakerCount": 2,
    "enrollmentIds": [
        "11788847407133"
    ],
    "insights": ["All"],
    "audioType": "CallCenter"
}

2. With "All" "Emotion" "Energy" insights:

{
    "contentUri": "file url",
    "encoding": "Mpeg",
    "languageCode": "en-US",
    "speakerCount": 2,
    "enrollmentIds": [
        "11788847407133"
    ],
    "insights": [
        "All",
        "Emotion",
        "Energy"
    ],
    "audioType": "CallCenter",
    "enableVoiceActivityDetection": true,
    "enablePunctuation": true,
    "enableSpeakerDiarization": true
}

Both cases returns response with empty insights:


Here are some more jobId's that we tried to get insights:
1. 04a7ceec-35e1-11ee-90cb-0050569cffc5

2. 0249cc0a-35e0-11ee-b580-0050569c72ca

3. 6fe183c8-35d8-11ee-b31c-0050569cffc5

Is there any way to request Interaction Analytics with emotion insights?
