Additional information:
The payload dialogflow send when using the API V2 is quite different from the one with the V1

Isn't this more of a feature request since the first one is supported? Might want to consider closing this and starting a feature request in the forum.

i am on debug now on version V2, and have some error on responses

Webhook call failed. Error: Failed to parse webhook JSON response: Cannot find field: displayText in message google.cloud.dialogflow.v2.WebhookResponse.

Until HA will not support V2, you can set agent to use V1 and let it works again - take a look on this:
https://dialogflow.com/docs/agents#settings
@dshokouhi at the moment I haven't seen any feature request for V2 so I will open it asap

There hasn't been any activity on this issue recently. Due to the high number of incoming GitHub notifications, we have to clean some of the old issues, as many of them have already been resolved with the latest updates.

Please make sure to update to the latest Home Assistant version and check if that solves the issue. Let us know if that works for you by adding a comment :+1:

Setting agent to use V1 , worked for me, thanks @miticojo

Dialogflow API V1 is deprecated and will be shut down on October 23th, 2019.

Is this still an issue you are experiencing? Can you please try upgrading to the latest version of Home Assistant (0.90) and report back if this is still a problem? Thanks!

[SteveEdson]

Still an issue, docs say it only supports v1. Any plans to update for V2?

This issue now has been marked as stale and will be closed if no further activity occurs. Thank you for your contributions.

[SteveEdson]

As far as I can tell, this is still an issue, and shouldn't be marked as stale.

Thanks

Any new agents created on dialogflow now default to V2 with NO option to revert to V1. So this is now a bug report in my view not a feature request as the feature no longer works with newly added agents.

Can't link dialogflow, error : Webhook call failed. Error: Failed to parse webhook JSON response: Expect message object but got: null.

[dedepene]

Now that V2 is the only option, I keep getting "Webhook call failed. Error: Failed to parse webhook JSON response: Expect message object but got: null."

Is this script supposed to work at all?

intent_script:
  GetTemperature:  # Intent type
    speech:
      text: We have {{ states.sensor.temperature }} degrees
    action:
      service: notify.notify
      data_template:
        message: Hello from an intent!
