{ "message" : "Required part file is missing", "code" : 34 }

**Describe the bug**
When attempting to make a curl request in terminal I get the following response:

```
{
"message" : "Required part file is missing",
"code" : 34
}
```

**To Reproduce**
Steps to reproduce the behavior:

run this in a terminal:

`curl -X POST http://localhost:8000/api/v1/recognition/recognize -H "x-api-key: 6b9cca31-a5fe-xxxx-xxxx-6373513a1f83" -H "Content-Type: multipart/form-data" -F file=person_1.jpg`

What am I doing wrong? I am trying to implement this API call in Python and am getting a 400 instead of a 200 and a result.

Start by reproducing the documented curl request against the /api/v1/recognition/recognize endpoint and inspect how the service handles the multipart upload. Compare the request with the API’s expected file input and verify the behavior from the terminal. Done means the same recognition request returns HTTP 200 with a result instead of HTTP 400.
