Thanks for your answer @bnusunny. Two follow-on questions. How is Is it possible to elaborate on what data should I be providing to the functions. How does the JSON payload map to something that the function handler can interpret? |

Sorry, this is probably a little off topic, but does this mean this "de-translation" introduces a little overhead? I'm very new to lambda (or the entire web development), sorry if my assumptions are wrong. Is |

Hey Tim! I was in the exact predicament as you a few weeks back.
Yes,
If you are using the curl -v -X POST \

-H 'content-type: application/json' \

"{
\"words\": [\"hello\", \"world\"],
\"number\": 5

struct RequestEvent {
words: Vec<String>,
number: i32
}
async fn handler(event: Request) -> Result<Response<Body>, Error> {
let payload = match event.payload::<RequestEvent>() {

I'm slightly confused about how to invoke the HTTP examples on the command line via
cargo lambda invoke.For example, the
http-axumexample provides a few HTTP accessible paths, but I'm unsure how to reach them.http-basic-lambdais even more frustrating, because it doesn't accept any arguments, yet theinvokesub-command requires that users specific data to sent.What data should I be providing? How do I send GET vs POST requests? Is it possible to simply use
