Enhance Exception Handling and Communication

[arkaprovob]

Description:
In certain exceptional cases, there is a lack of proper communication of error messages to the API consumer. To enhance consumer experience and error handling, implement a mechanism, preferably using Server-Sent Events (SSE) or a Redis queue, to send formatted exception messages to the consumer when an exception occurs during command execution.

Benefits:

• Improved error handling and api consumer experience.
• Clear and informative error messages for API consumers.

Implementation:

1. Implement a mechanism (SSE or Redis queue) Use SSE for now till we implement Redis to send exception messages to the API consumer.
2. Ensure that exception messages provide detailed information about the encountered error.
