# 无效输入
<a name="attribute-trans-invalid"></a>

以下示例显示了无效输入。在这种情况下，JSON 对象向 SIP 媒体应用程序传递的项目过多。

```
{ 
    "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}}" 
    } 
}
```

以下示例显示了对先前给定输入的响应。此输出从 SIP 媒体应用程序传回调用该应用程序的 AWS Lambda 函数。
