I'm receiving the following error, whenever Im using SSML in my Dialogflow output (V2):

Error: string required by Text constructor. at new Text (/text-response.js:48:13)

@LukeJanissen Can you provide your code and more information?

LukeJanissen commented 6 years ago

@sarahdwyer Of course! Whenever I'm using SSML code in the audio output section of the Google Assistant response in Dialogflow, my webhook returns the error I mentioned above. This happens at the moment I'm declaring new WebhookClient({request: request, response: response}) (not even calling it). I already stripped my entire code, so the only thing it would do is send a exact copy of the request back. This works as long as I'm not declaring new WebhookClient, but I will need the SDK to add certain functionality to my webhook.

@LukeJanissen Do you have text-to-speech functionality and beta features enabled from settings?

I have the same issue, the error happends without my code, just when new WebhookClient({request: request, response: response}) is invoked (first line of webhook fulfillment. What can I do?

I'm having the same problem. According to Firebase logs the problem is nowhere in my code image

Solved! The problem start in Dialogflow. Go to your intent and remove Google Assistant responses you've configured. I don't know why but the Google Assistant payloads and v2 agent are incompatibles right now.

If you remove it, payload will fix the issue and Webhook constructor works fine!
