# Invalid Request

The request is malformed and cannot be processed by the server. This typically means the request body, headers, or content type are incorrect.

**HTTP Status:** `400 Bad Request`

## Error Codes

| Code | Description |
|  --- | --- |
| `invalid_content_type` | The `Content-Type` header is missing or not supported |
| `malformed_body` | The request body is not valid JSON |
| `missing_file` | A required file upload is missing |


## Example Response


```json
{
  "type": "https://api.dinie.com.br/errors/malformed_body",
  "title": "Bad Request",
  "status": 400,
  "detail": "The request body could not be parsed as JSON.",
  "code": "malformed_body"
}
```

## How to Resolve

- **`invalid_content_type`** -- Set the `Content-Type` header to `application/json` for JSON requests or `multipart/form-data` for file uploads.
- **`malformed_body`** -- Validate that your request body is well-formed JSON before sending. Check for trailing commas, unquoted keys, or encoding issues.
- **`missing_file`** -- Ensure the required file field is included in your multipart upload.
