Having trouble registering a user in the following code:

```auto
const client = new AmityClient({apiKey, apiEndpoint})
        const success = wait client.registerSession({userId})
        console.log(success)

```

The error is:

1. XHRPOST  
[http://wowness.local/eu/api/v4/sessions](http://wowness.local/eu/api/v4/sessions)  
[HTTP/1.1 404 Not Found 19ms]

2. Uncaught (in promise) TypeError: can’t access property “code”, t.t0.response.body is null

I need help

Hello,

Could you please verify your apiEndpoint once more? It is recommended that the apiEndpoint be ‘[https://api.eu.amity.co](https://api.eu.amity.co/)’ instead of ‘[http://wowness.local](http://wowness.local/)’. If you have any questions or need further assistance, feel free to let us know.

Best regards,

Support Team
