# Action `operator_panel__get_last_dialog`

> **System ID:** `action_operator_panel__get_last_dialog`  
> In the scenario also: `operator_panel__get_last_dialog`

## Description

Finds the last Operator Panel chat room for the current `chat_id` and channel, loads messages and participants, and writes the result to a constant. Format: JSON (string) or text (`txt`). Default constant — `last_operator_dialog`, unless `set_to` is set.

## Events (scenario branches)

| Event | When it occurs |
|-------|----------------|
| **success** | Chat room found; result (if there are messages) written to the constant |
| **error** | Chat room not found |

If the room exists but has no messages, the action may still return **success**, and the constant may stay without a new value.

## Parameters

| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| `format` | string | no | `json` | Output format: `json` or `txt` |
| `set_to` | string | no | — | Constant name for the result; if missing — `last_operator_dialog` |

## Configuration example

```json
{
  "format": "json",
  "set_to": "dialog_history"
}
```

Text variant:

```json
{
  "format": "txt",
  "set_to": "dialog_text"
}
```
