Streaming example: implement onerror()

[tomerweller]

The current streaming example doesn't implement the onerror() callback. In production this means that the subscriber can loose connection without knowing about it.

My background and how it can be leveraged

I am a frontend and blockchain developer.
By applying my knowledge and experience, I can ensure robust and resilient streaming connections, minimizing downtime and providing seamless user experiences.

How I plan on tackling this issue

Implement the onerror() callback in the streaming example to catch and handle errors.
2. Log errors and provide meaningful feedback to the subscriber.
3. Develop a reconnect mechanism to automatically re-establish the connection.
