I am doing api testing with Jmeter and using json path assertion to the response body. Problem is response body is giving two response path based on success and failure.

```
{
    "response": {
        "error_message": "Invalid input data.",
        "error_code": "Invalid_input",
        "error": true
    }
}

```

> 
> for success
> 
> 
> 

```
{
    "response": [
        {
            "attachment_name": "num1.png",
            "attachment_id": 2547,
            "error": false
        },
        {
            "attachment_name": "num2.png",
            "attachment_id": 2548,
            "error": false
        },
        {
            "attachment_name": "num3.png",
            "attachment_id": 2549,
            "error": false
        }
    ]
}

```

Here am adding assertion on "error" path and value but the path changes on the result. 
Added `$.response.error` but this works only for failure case

Please help me to get correct path and assert in both the conditions. Thanks.
