[REFACTOR] Add Validation on response  #5

Enhance the check_execution_status method by adding validation for responses before attempting to parse them with response.json. This will ensure more robust error handling and prevent issues with invalid or null responses.

Requirements

• Verify the response status code after requests.get.
• Check for None or empty response content before calling response.json.
• Would be better a status code check here.
• Implement appropriate logging or error handling if the response is invalid.
