Uncaught Error: java.lang.String cannot be cast to java.lang.Double

import { FacebookAds } from 'expo'
import AdScreenFacebook from './AdScreenFacebook'
class AdScreen extends React.Component {
render () {
return (
<AdScreenFacebook adsManager={adsManager} adChoicePosition="topLeft" expandable={false} />
);
}
}
// AdScreenFacebook.js
import React from 'react';
import { FacebookAds } from 'expo'
const { AdIconView, AdMediaView } = FacebookAds;
const adsManager = new FacebookAds.NativeAdsManager("2272791379702600_2272795453035526", "1");
class AdScreenFacebook extends React.Component {
render () {
return (
<View>
<AdMediaView />
<AdTriggerView>
<Text>{this.props.nativeAd.bodyText}</Text>
</AdTriggerView>
</View>
);
}
}
export default FacebookAds.withNativeAd(AdScreenFacebook);
export default createStackNavigator(
{
Main: {
screen: AdScreen,
},
AdScreenFacebook: {
screen: AdScreenFacebook,
}
},
{
initialRouteName: 'Main',
}
);

Answer 1

Remove the quotation marks from the number 1 in the NativeAdsManager function. You are currently passing that function the number 1 as a string instead of as a number.
// AdScreenFacebook.js
const adsManager = new FacebookAds.NativeAdsManager("2272791379702600_2272795453035526", 1);

Answer 2

With SDK 33, we’re deprecating imports of most modules from the expo package. This means that in a future release, you won’t be able to write, for example, import { FacebookAds } from 'expo';. Rather, you’ll need to install the individual packages for each module you use and import from them instead.
You can use the new expo install command to install modules; this command is a wrapper around npm install/yarn add that automatically installs a module version compatible with your SDK version. For example, for the FacebookAds module, you would run expo install expo-ads-facebook and then use import * as FacebookAds from 'expo-ads-facebook';. This change paves the way for tree-shaking and smaller JavaScript bundles. It also makes moving between the managed and bare workflows simpler.
If you want to use a Expo module such as a question, install it and set it up.
For managed apps, you'll need to run expo install expo-ads-facebook. To use it in a bare React Native app, follow its installation instructions.
Usage
import * as FacebookAds from 'expo-ads-facebook';
const { AdTriggerView, AdMediaView } = FacebookAds;
class AdComponent extends React.Component {
render() {
return (
<View>
<AdMediaView />
<AdTriggerView>
<Text>{this.props.nativeAd.bodyText}</Text>
</AdTriggerView>
</View>
);
}
}
export default FacebookAds.withNativeAd(AdComponent);
