Prompts not working

[AndyTheNest]

Hi!

I have a test page with both the iFrame based demo chatbot and an implementation using apiai-javascript-client, side by side.

I have a weather fulfillment example running like in the api.ai docs. This gives the weather based on city + date. I have the date set up to be required with a prompt "On what day?".

On the iFrame based one it works correctly:

what is the weather in sydney? On what day? sunday The weather forecast for the City of Sydney, Australia on 2017-10-01 is Sunny with a projected high of 22°C or 72°F and a low of 15°C or 58°F.

On the apiai-javascript-client one this happens:

what is the weather in sydney? On what day? sunday I missed what you said. Say it again?

So the context of the conversation does not appear to be maintained? Is this not supported, or am I doing it wrong?

I'll include an excerpt from my code below.

Thanks!

var token = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';

//handles call and response from chatbot API
function askQuestion(question) {
	log('Calling API');

	const client = new ApiAi.ApiAiClient({accessToken: token});
	const promise = client.textRequest(question);

	promise
		.then(handleResponse)
	    .catch(handleError);

	function handleResponse(serverResponse) {
		log('Response OK');
		var answer = serverResponse.result.fulfillment.speech;
		$('#question-answer').text(answer);
		$('#question-text').val('');								
		log('Done');
	}
	function handleError(serverError) {
		log('ERROR ON API CALL');
		log(serverError);
	}
}

//logs messages with appending on by default
function log(message, clearLog = false) {
	if(clearLog) {
		$('#question-log').text(message)
	}
	else {
		$('#question-log').append('<br />' + message);
	}
}

//main
$(document).ready( 
	function() {

		//handle button click
		$('#question-button').click(
			function() {
				$('#question-answer').text('');									
				log('Started', true);

				var question = $('#question-text').val().trim();
				if(question==='') {
						log('Validation failed');
				}
				else {
						askQuestion(question);
				}

			}
		);

	}
);

Okay, after a coupe of weeks I came back to this and saw the problem immediately.

This line const client = new ApiAi.ApiAiClient({accessToken: token}); ...needed to be moved out of the askQuestion function, so that the client is only created once per session. Then the context works fine.
