# range-too-short

The time range is **too short for the number of events**.

- **Status:** `422 Unprocessable Entity`
- **Route:** `POST /api/v1/generate-events`
- **Description:** `range is too short for the event count: expected a longer range or fewer events`
- **Details:** **`eventCount`**, **`from`**, and **`to`**, as the request gave them.

## Why It Happens

- Even the **largest population** that SynthEvents sizes, with as many members as events asked for, comes out at too few events in this range: in so short a range, hardly anybody does anything. Asking for 20,000 events of the to-dos within a single minute, for example, is refused this way.
- The run comes out at **no events at all**. An empty data set is never what anybody asks for, so it is refused, too.

## How to Fix It

Make the range longer, or ask for fewer events. For how SynthEvents sizes a run, see **[The Number of Events](/docs/synthevents/generating-data-sets#the-number-of-events)**.

## Example

For 20,000 events of the to-dos within a single minute, SynthEvents answers:

```json
{
  "type": "error",
  "data": {
    "code": "https://docs.synthevents.io/errors/range-too-short",
    "description": "range is too short for the event count: expected a longer range or fewer events",
    "details": {
      "eventCount": 20000,
      "from": "2025-01-01T00:00:00Z",
      "to": "2025-01-01T00:01:00Z"
    }
  }
}
```
