# data-set-missing

The request names **no data set**.

- **Status:** `400 Bad Request`
- **Route:** `QUERY /api/v1/read-data-set`
- **Description:** `data set is missing: expected the name of a data set that read-domains lists`
- **Details:** Empty.

## Why It Happens

The body has no field `name`, or its value is `null`.

## How to Fix It

Add the field `name`, with the name of a ready-made data set. **[`read-domains`](/docs/synthevents/api#reading-domains)** lists them for every scenario:

```json
"name": "library-everyday-medium"
```
