    class ExecutionResult {
      name!: string;
      proxyMessage!: string;
    }

    const url = "https://swapi.dev/api/planets/1/";
    const response = proxyHttpFetch(url);

    if (response.ok) {
      const proxyMessage = generateProxyHttpSigningMessage(url, "GET", Bytes.empty(), response.bytes);
      const data = response.bytes.toJSON<ApiResponse>();

      Process.success(Bytes.fromJSON<>({ name: data.name, proxyMessage: proxyMessage }));
    } else {
