The `JsonResponse` is already setting the content type of the response. Do not redefine the content type being sent.

## Non-Compliant Code Examples{% #non-compliant-code-examples %}

```python
import json

from django.http import HttpResponse

response_data = {}
response_data['result'] = 'error'
response_data['message'] = 'Some error message'
return JsonResponse(response_data, content_type="application/json")  # content-type is not necessary for JsonResponse
```

## Compliant Code Examples{% #compliant-code-examples %}

```python
import json

from django.http import HttpResponse

response_data = {}
response_data['result'] = 'error'
response_data['message'] = 'Some error message'
return JsonResponse(response_data)  # content-type is not necessary for JsonResponse
