unable to hit external API from SPIN Go component running in SpinKube

What were you doing

Trying to run a simple SPIN Go component in Kubernetes that hits an external (third party) API .

What did you expect

Component to hit the cat facts public API (https://catfact.ninja/fact) and return a fact that would then be sent to the end user

What happened

The component seems to thrown a " Runtime error" on the following line. Not additional logs printed.

req, err := spinhttp.Get("https://catfact.ninja/fact")

Additional Info

Component runs fine locally outside of k3d
Able to run other components in K8s that do not try to hit an external API
Able to run another container (non-wasm) in the cluster and get the appropriate response from the cat fact api

Steps to reproduce

Create a simple http-go sample application

spin new -t http-go --accept-defaults simple-get-go

change the contents of the init function in the main.go file to :

func init() {
    spinhttp.Handle(func(w http.ResponseWriter, r *http.Request) {

        req, err := spinhttp.Get("https://catfact.ninja/fact")
        if err != nil {
            fmt.Printf("Problem getting cat fact. %s\n", err.Error())
            http.Error(w, err.Error(), http.StatusInternalServerError)
            return
        }

        decoder := json.NewDecoder(req.Body)
        newFact := struct {
            Fact   string `json:"fact"`
            Length int    `json:"length"`
        }{}

        err = decoder.Decode(&newFact)
        if err != nil {
            log.Println(err)
            return
        }

        w.Header().Set("Content-Type", "text/plain")
        fmt.Fprintln(w, newFact.Fact)
    })
}

Push container to the image repository

spin registry push --build bolbeck/simple-get-go

Scaffold the K8s manifest

mkdir k8s
spin kube scaffold --from bolbeck/simple-get-go --out k8s/simplegetgo.yaml

Deploy the container to k3d and port forward to it:

 kubectl apply -f k8s/simplegetgo.yaml       
kubectl port-forward svc/simple-get-go 8083:80

Navigate to localhost:8083 in the browser (or curl it) and the application throws a "Runtime error" message

Environment

k3d version v5.6.0 k3s version v1.27.5-k3s1 (default) spin-operator 0.1.0

What is the best way to debug this in K3d given that the WASM container does not have a distro and thus I assume one cannot log into the container?
