        })
        
        model = 'anthropic.claude-v2:1'
        
        response = self.bedrock.invoke_model(body=body, modelId=model, accept='application/json', contentType='application/json')
        
        return response
    
    async def validate_claude_response(self, system_prompt, user_prompt, retry_count: int = 5):        
        for attempt in range(retry_count):
            try:
                claude_response = await self.async_request_to_claude(
                    system_prompt, user_prompt
                )
                if claude_response:
                    content = json.loads(claude_response.get('body').read())['completion']
                    response = json.loads(content)
                    return response
            except Exception as e:
                logger.info("Trying again after 3 seconds - %s", e)
                await asyncio.sleep(3)
        # Additional error handling and logging can be implemented here

This client class provides methods to send asynchronous requests to Claude 2.1 and handle responses, including built-in retry logic to manage potential network issues or rate limiting.
