Exception 'Project ID path component of DSN is missing'

I’m integrating Sentry with my React Native project.
After iOS simulator wakes up, I get this error.

Here is what I wrote down on my App.js

import { Sentry } from 'react-native-sentry'


export default class MyApp extends component {

I suppose this line is where the error is thrown ↓↓

But, I couldn’t figure out what pathComponents mean.

Any idea solving the problem?
