Bug: Base HTTP gateway resolver sample fails

[andreacfm]

Expected Behaviour

The error happens both with 3.0.0 than with 2.43.1

Current Behaviour

The base sample from the handler docs for Api HTTP Gateway returns the following 500 error.

[ERROR] KeyError: 'http'
Traceback (most recent call last):
  File "/var/task/app.py", line 26, in lambda_handler
    return app.resolve(event, context)
  File "/var/task/aws_lambda_powertools/event_handler/api_gateway.py", line 2100, in resolve
    response = self._resolve().build(self.current_event, self._cors)
  File "/var/task/aws_lambda_powertools/event_handler/api_gateway.py", line 2194, in _resolve
    method = self.current_event.http_method.upper()
  File "/var/task/aws_lambda_powertools/utilities/data_classes/api_gateway_proxy_event.py", line 317, in http_method
    return self.request_context.http.method
  File "/var/task/aws_lambda_powertools/utilities/data_classes/common.py", line 467, in method
    return self["requestContext"]["http"]["method"]

Code snippet

from requests import Response

from aws_lambda_powertools import Logger, Tracer
from aws_lambda_powertools.event_handler import APIGatewayHttpResolver
from aws_lambda_powertools.logging import correlation_paths
from aws_lambda_powertools.utilities.typing import LambdaContext

tracer = Tracer()
logger = Logger()
app = APIGatewayHttpResolver()


@app.get("/todos")
@tracer.capture_method
def get_todos():
    todos: Response = requests.get("https://jsonplaceholder.typicode.com/todos")
    todos.raise_for_status()

    # for brevity, we'll limit to the first 10 only
    return {"todos": todos.json()[:10]}


# You can continue to use other utilities just as before
@logger.inject_lambda_context(correlation_id_path=correlation_paths.API_GATEWAY_HTTP)
@tracer.capture_lambda_handler
def lambda_handler(event: dict, context: LambdaContext) -> dict:
    return app.resolve(event, context)

Ciao @andreacfm, thanks for opening this issue! I couldn't reproduce the error and I'm wondering if you are using Payload v1.0 in this integration. You should use Payload v2.0 to use this Resolver. Payload v1.0 is supported in APIGatewayRestResolver, but I recommend you to use Payload v2.0 in HTTP API.

I would also like to ask if you are using Terraform to deploy this workload, because this is a known issue that Terraform defaults to Payload v1.0 if the version is not provided.

Please let me know if changing the version fixed the problem and if I can help with anything else.

@leandrodamascena my bad. I was using 1.0 payloads. Thanks for checking in.
