Suppress "WARNING: Invalid HTTP request received." warning

[hiraken-w]

The following log may be recorded in the Application log output to CloudWatch Logs when the AgentCore runtime starts up.
When recorded during initialization after deployment, this is a message that does not affect the application. However, this could confuse users, so I would like to suppress it.

For example, you can confirm this log message by adding a lifespan to strands_claude.py as follows:

from contextlib import asynccontextmanager
from typing import AsyncGenerator

from strands import Agent, tool
from strands_tools import calculator # Import the calculator tool
import argparse
import json
from bedrock_agentcore.runtime import BedrockAgentCoreApp
from strands.models import BedrockModel

@asynccontextmanager
async def lifespan(_app: BedrockAgentCoreApp) -> AsyncGenerator[None, None]:
    """Completely empty lifespan context manager for testing."""
    yield
app = BedrockAgentCoreApp(lifespan=lifespan)

# Create a custom tool 
@tool
def weather():
    """ Get weather """ # Dummy implementation
    return "sunny"
