Hello, while using sonnet, I was referring to "python/example_code/bedrock-runtime/models/anthropic/claude3_chatbot_demo/0_try_claude3.py." However, there is a part where the model error is intermittent, has this error ever occurred? I don't know if it's right to leave it here, but I'd appreciate it if you could let me know if there's anything wrong with my code.
