ERROR TypeError: Cannot read property 'getInstance' of undefined, js engine: hermes

[Ankush-Hegde]

i was referring the pusher official doc and implemented as it was given. I wanted to implement the chat feature for the react native expo app.When i used this code I got the error.

const pusher = Pusher.getInstance();

await pusher.init({
apiKey: API_KEY,
cluster: API_CLUSTER
});

await pusher.connect();

ERROR TypeError: Cannot read property 'getInstance' of undefined, js engine: hermes
ERROR Invariant Violation: "main" has not been registered. This can happen if:

• Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current project.
• A module failed to load due to an error and AppRegistry.registerComponent wasn't called., js engine: hermes

if i remove that code everything works fine
