Description
What were you searching in the docs?
I was looking for an example to test my new lambda function that I used API Gateway HTTP API and the exampled provided was not working.
The example in docs is this:
@pytest.fixture
def lambda_context():
@dataclass
class LambdaContext:
function_name: str = "test"
memory_limit_in_mb: int = 128
invoked_function_arn: str = "arn:aws:lambda:sa-east-1:123456789012:function:test"
aws_request_id: str = "cdf446432739-2ce8-b7e4-f6d2-3db856ad"
return LambdaContext()
def test_lambda_handler(lambda_context):
minimal_event = {
"path": "/todos",
"httpMethod": "GET",
"requestContext": {"requestId": "227b78aa-779d-47d4-a48e-ce62120393b8"}, # correlation ID
}
ret = assert_http_response_module.lambda_handler(minimal_event, lambda_context)
assert ret["statusCode"] == 200
assert ret["body"] != ""And this was the result:

Is this related to an existing documentation section?
How can we improve?
What I made was debuging the errors and made a new `minimal_event` dict. What I cannot do for now (because of time - and two kids) is to find if it was a Documentation error or a code error.Got a suggestion in mind?
What I do to resolve the problem is to change the minimal_event dict to this:
minimal_event = {
"rawPath": "/todos",
"requestContext": {
"http": {
"method": "GET",
},
"stage": "$default",
},
}And the result now was this:
