Error: No Fill

**I dont know why i getting this error.**

**AdSetting:**

I use this in my startup file (index.js)

```
import { AdSettings } from 'react-native-fbads';
let hash = AdSettings.currentDeviceHash;
AdSettings.addTestDevice(hash); // i also used string from console too
```

**Usage:**

`import { InterstitialAdManager } from 'react-native-fbads';`

```
InterstitialAdManager.showAd(placementId) // i tried this format TEST_AD_TYPE#YOUR_PLACEMENT_ID
.then((didClick) => console.log(didClick))
.catch((error) => console.log(error));
```

Packages:

```
"react": "17.0.2",
"react-native": "0.67",
"react-native-fbads": "^7.0.5",
```

I also tried this dependency in gradle file:

`implementation 'com.facebook.android:audience-network-sdk:6.8.0'`
