# `INJECUTE_EXTENSION_RESULT`

**An extension returned a container that is not this one or its child.**

## How to fix it

A module function must return the registry it received (after adding services) or a fork of it.

## Handling it in code

```ts
import { InjecuteError } from 'injecute';

try {
  // ...
} catch (error) {
  if (error instanceof InjecuteError && error.code === 'INJECUTE_EXTENSION_RESULT') {
    // error.message explains what happened; error.path is the resolution chain
  }
}
```
