Response generation

Synchronous call

During a synchronous call, the bot cannot perform other reactions or respond to user requests until it gets a response from the knowledge base.

Within chat

state: Answer
    intent!: /question
    scriptEs6:
        try {
            // If there is no chat yet, the bot creates a new chat in the knowledge base
            $client.chat = $client.chat || await $rag.chat.create("MyKnowledgeHub");
            // The bot gets response from the knowledge base
            var chatResponse = await $rag.chat.processQuery(
                "MyKnowledgeHub", $client.chat.id, $request.query
            )
            if (chatResponse.status === "FINISHED") {
                // Send response to the user
                $reactions.answer(chatResponse.response);
            } else {
                // Error message if the status is not FINISHED
                $reactions.answer("Sorry, something went wrong. Status: " + chatResponse.status);
            }
        } catch (error) {
            // Error message if the bot failed to send the request
            $reactions.answer("An error occurred: " + error);
}

In this example, the bot:

1. If there is no chat yet, creates a new chat using $rag.chat.create.

2. Gets the response using the $rag.chat.processQuery method. The bot calls the method synchronously using await.

   caution

   If the knowledge base generates a response for more than 25 seconds, then the bot will not receive it. In this case, call the method asynchronously.

3. Sends a response or error message.

Single request

    scriptEs6:
        try {
            // The bot gets the response from the knowledge base
            var ragResponse = await $rag.query.generateAnswer("MyKnowledgeHub", $request.query);
            if (ragResponse.status === "FINISHED") {
                // Send the response to the user
                $reactions.answer(ragResponse.response);
            } else {
                // Error message if the status is not FINISHED
                $reactions.answer("Sorry, something went wrong. Status: " + ragResponse.status);
            }
        } catch (error) {
            // Error message if the bot failed to send the request
            $reactions.answer("An error occurred: " + error);
}

In this example, the bot:

1. Gets the response using the $rag.query.generateAnswer method. The bot calls the method synchronously using await.

   caution

   If the knowledge base generates a response for more than 25 seconds, then the bot will not receive it. In this case, call the method asynchronously.

2. Sends a response or error message.

Asynchronous call

During an asynchronous call, the bot can continue to respond to user requests even if it has not yet received a response from the knowledge base.

Within chat

        # If the user asks a question while waiting, the bot will be able to answer it instantly
        state: Waiting
            q!: No answer yet?
            a: Just one more minute…

knowledgeHub.js

async function sendRequest(secretName, query) {
    try {
        // If the chat does not exist yet, the bot creates a new chat in the knowledge base
        $client.chat = $client.chat || await $rag.chat.create(secretName);
        // The bot gets the response from the knowledge base
        var chatResponse = await $rag.chat.processQuery(
                secretName, $client.chat.id, query
            );

        if (chatResponse.status === "FINISHED") {
            // Send the response to the user
            $conversationApi.sendTextToClient(chatResponse.response);
        } else {
            // Error message if the status is not FINISHED
            $conversationApi.sendTextToClient("Sorry, something went wrong. Status: " + chatResponse.status);
        }
    } catch (error) {
        // Error message if the bot failed to send the request
        $conversationApi.sendTextToClient("An error occurred: " + error);
    }
}

export default {
    sendRequest
};

In this example, the bot:

1. If there is no chat yet, creates a new chat using $rag.chat.create.
2. Gets the response using the $rag.chat.processQuery method. The method is called asynchronously, inside the asynchronous sendRequest function.
3. Sends a response using $conversationApi.sendTextToClient.

Restrictions

• This script is not supported in the phone channel.
• If the knowledge base does not generate an answer within 2 minutes, an error will occur.
