Trying to Broadcast an iBeacon using React Native

I am trying to create a simple app using React Native that broadcasts an iBeacon. I have found a possible third-party module called react-native-ibeacon-simulator but even a simple test fails. I know this has not been updated for some time however I can't find a better solution...

I saved the index.ios.js file as iBeacon.js

import React, { Component } from 'react'
import { Text, View } from 'react-native'
import ibeacon from './ibeacon'

export default class App extends Component {
    componentWillMount() {
        const uuid = '04bc1d42-98be-4031-a4a9-50c76cb3e1b9'
        const identifier = 'com.myapp'
        ibeacon.startAdvertisingBeaconWithString(uuid, identifier, 0, 0)
    }
    render() {
        return (<View><Text>iBeacon</Text></View>)
    }
}

However I get the following error in the terminal (and on the screen of the connected iPhone 6S running iOS13:

Warning: %s: Error boundaries should implement getDerivedStateFromError(). In that method, return a state update to display an error message or fallback UI., RootErrorBoundary

I've tried debugging but can't figure out why this is happening...
