Why are the responses different between onsite agent and Node?

[DirkWolthuis]

Why does api.ai does not register intent when I ask a question via my node app (FB-messengerbot)? If I ask the same question via the agent on the website it does register the intent.

Hi,

Can you send me example of code and intent information? Which language you use?

[DirkWolthuis]

Hi. I'm using Dutch as the language. Stuff like dates are working in the onsite agent. If I use for example 12 juli, it works even if I haven't added that exact date. But via my Facebook Messenger bots I does not recognize the prompt input.

This is a other example of differences:

I don't think it has anything to do with my code as it just sends the feedback form your API.

Hi, @DirkWolthuis Do you use custom bot implementation or start the bot from api.ai?

If you ran it on Heroku, please send me list of the app parameters. It should contain APIAI_LANG parameter with value nl.

Thanks, Danil.

Hi, sorry for the late reaction. I don't use a custom implementation. I made a video to show you the differences. And I will post the code from the bot here. I hope you can help me to identify the problem.

Hi, @DirkWolthuis I don't see language parameter in your code.

Could you please try to change

var ai = apiai("CODE");

to

var ai = apiai("CODE", {language: "nl"});

Language parameter is required for non-English agents.

[DirkWolthuis]

Thanks! That solved it. Thanks! Hmm, but know the stop command does not work. Is there a dutch alternative?

[xVir]

Do you mean phrase for resetting parameters? "Cancel" word also not working?

[DirkWolthuis]

Nope also not working.

[xVir]

Ok, let me check this case. Thanks.
