# Variable: E\_INVALID\_INITIAL\_THOUGHT\_VALUE

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

Defined in: [lib/exceptions/runtime.ts:218](https://github.com/NHTIO/ADK/blob/v1.20260605.0/src/lib/exceptions/runtime.ts#L218)

Thrown when a [@nhtio/adk!Thought](../../common/classes/Thought.md) is initialised with a value that fails schema validation.

## Remarks

`Thought` requires `id`, `content`, `createdAt`, and `updatedAt` to be present and of the
correct type. Passing an incomplete or incorrectly typed object signals a programming error
in the caller, not a recoverable runtime condition.
