Add handling for when Instance_id is passed, but is Invalid

[dheerajoruganty]

Description:

If an Instance_id is passed and it is invalid (e.g., the instance does not exist, has been terminated, or the Instance_id format is incorrect), the process currently fails and stops execution.

Scenarios Where This Might Occur:

• A previously created instance has been terminated or deleted but its Instance_id is still referenced.
• An incorrectly formatted or non-existent Instance_id is passed.
• The Instance_id belongs to a different region than the one the API is targeting.

Steps to Reproduce:

1. Pass an invalid Instance_id to an API call.
2. Observe the process halt due to an error response from the API.

Expected Behavior:

• The system should catch the error if the Instance_id is invalid.
• The error should be logged with sufficient details (e.g., invalid ID, reason for failure).
• The script should skip the invalid Instance_id and continue with other valid instances.

Possible Solutions:

• Implement try-catch (or equivalent) error handling for operations involving Instance_id.
• When an invalid Instance_id is detected, log the error, and move on to the next instance.
• Ensure that the error handling works across different operations (e.g., start, stop, terminate, etc.).
