# SKAdTestError.Code.invalidConversionValue

The conversion value isn’t valid, in the testing environment.

```
case invalidConversionValue
```

## Discussion

This error isn’t used. If your conversion value isn’t valid, the unit test shows the <doc://com.apple.documentation/documentation/StoreKit/SKANError-swift.struct/Code/invalidConversionValue> error instead, but only if your app calls <doc://com.apple.documentation/documentation/StoreKit/SKAdNetwork/updatePostbackConversionValue(_:completionHandler:)>.
