# Invalid inputs


The following example shows an invalid input. In this case, the JSON object passes too many items to a SIP media application.

```
{ 
    "SchemaVersion": "1.0", 
    "Actions": [ 
        { 
            "Type": "PlayAudio", 
            "Parameters": { 
                "ParticipantTag": "LEG-A", 
                "AudioSource": { 
                    "Type": "S3", 
                    "BucketName": "mtg1-sipmedia-app-iad", 
                    "Key": "Welcome3.wav" 
                } 
            } 
        } 
    ], 
    "TransactionAttributes": { 
        "key1": "value1", 
        "key2": "value2", 
        "key3": "value3", 
        "key4": "value4", 
        "key5": "value5", 
        "key6": "value6", 
        "key7": "value7", 
        "key8": "value8", 
        "key9": "value9", 
        "key10": "value10", 
        "key11": "value11" 
    } 
}
```

The following example shows the response to the previously given input. This output is passed from a SIP media application back to the AWS Lambda function that invoked the application.
