Self Hosted Restify Server

Hi,

I'm trying to use the @assistant/conversation in restify, But I get this error:

(node:17) UnhandledPromiseRejectionWarning: Error: Handler not found for handle name: at Function.handler (/app/node_modules/@assistant/conversation/dist/conversation/conversation.js:109:23) at Function.standard [as handler] (/app/node_modules/@assistant/conversation/dist/assistant.js:49:32) at omni (/app/node_modules/@assistant/conversation/dist/assistant.js:41:20) at nextTick (/app/node_modules/restify/lib/chain.js:167:13) at process._tickCallback (internal/process/next_tick.js:61:11) (node:17) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 2) (node:17) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

Example:

// Import the appropriate service and chosen wrappers
const {
    conversation,
    Image,
    Card
} = require('@assistant/conversation');

// Create an app instance
const app = conversation({ });

app.handle('greeting', conv => {
    conv.add('Hi, how is it going?')
    conv.add(new Image({
      url: 'https://developers.google.com/web/fundamentals/accessibility/semantics-builtin/imgs/160204193356-01-cat-500.jpg',
      alt: 'A cat',
    }));
});

// ... restify code

server.post('/assistant', app);

I use the restify bodyParser

server.use(restify.plugins.bodyParser({ maxBodySize: 1000000 }));

Look like some JSON parser problem. JSON parse on body by restify:

{"handler":{"name":"greeting"},"intent":{"name":"YES","params":{},"query":"Sim"},"scene":{"name":"Start","slotFillingStatus":"UNSPECIFIED","slots":{},"next":{"name":"actions.scene.END_CONVERSATION"}},"session":{"id":"ABwppHHi7JYqhUAqDyFt63dcPtQ0or_Lx4ILhgWqoscrfrX74j2aECq4yHVPlPbloQ_uidDNS4swocEGjsletXOAt5E_RA7Z","params":{},"typeOverrides":[],"languageCode":""},"user":{"locale":"pt-BR","params":{},"accountLinkingStatus":"ACCOUNT_LINKING_STATUS_UNSPECIFIED","verificationStatus":"VERIFIED","packageEntitlements":[],"lastSeenTime":"2020-10-08T09:32:08Z"},"home":{"params":{}},"device":{"capabilities":["SPEECH","RICH_RESPONSE","LONG_FORM_AUDIO"]}}

console.log(`HANDLER NAME: ${req.body.handler.name}`); HANDLER NAME: greeting

Without '@assistant/conversation' works fine: Example:

server.post('/assistant', (req, res, next) => {
        res.json({
            "session": {
              "id": "example_session_id",
              "params": {}
            },
            "prompt": {
              "override": false,
              "content": {
                "card": {
                  "title": "Card Title",
                  "subtitle": "Card Subtitle",
                  "text": "Card Content",
                  "image": {
                    "alt": "Google Assistant logo",
                    "height": 0,
                    "url": "https://developers.google.com/assistant/assistant_96.png",
                    "width": 0
                  }
                }
              },
              "firstSimple": {
                "speech": "This is a card rich response.",
                "text": ""
              }
            }
          }
        );
        return next();
    });
