# Variable: E\_LLM\_EXECUTION\_EXECUTOR\_ERROR

```ts
const E_LLM_EXECUTION_EXECUTOR_ERROR: CreatedException<[]>;
```

Defined in: [lib/exceptions/runtime.ts:542](https://github.com/NHTIO/ADK/blob/v1.20260605.0/src/lib/exceptions/runtime.ts#L542)

Emitted (via the observability `error` hook) and re-thrown when the user-supplied executor
callback throws during [@nhtio/adk!DispatchRunner.dispatch](../../dispatch_runner/classes/DispatchRunner.md#dispatch).

## Remarks

Not fatal — executor errors are recoverable runtime conditions. `dispatch()` rejects with this
exception so callers can handle the failure via try/catch.
