# `EMPTY_DOCUMENT`

`EMPTY_DOCUMENT`

## Description

The `document` part of the request holds no byte. An empty document has a fingerprint, but it proves nothing.

## HTTP Status

`422 Unprocessable Entity`

## `doc_url` Format

The `doc_url` value is an absolute URL and changes by environment:

`<docs-base-url>/errors/empty_document`

## Typical Causes

* The client sent the part before it read the file.
* The file on the disk of the client is empty.

## Example

Request: `POST /v1/certification/certifications` with an empty `document` part.

Response:

```json
{
  "errors": [
    {
      "code": "EMPTY_DOCUMENT",
      "message": "The document holds no byte",
      "doc_url": "https://docs.example.com/errors/empty_document"
    }
  ]
}
```

## How To Fix

1. Check that the file holds at least 1 byte.
2. Send the request again with a new idempotency key.
