# missingWinningPostback

The testing environment is missing a winning postback.

```
static var missingWinningPostback: SKAdTestError.Code { get }
```

## Discussion

Check that the first postback in the `postbacks` array you set when calling [`setPostbacks(_:)`](/documentation/StoreKitTest/SKAdTestSession/setPostbacks(_:)) has `didWin` set to `true`.
