Got the “My test app isn't responding right now. Try again soon.” error message even a clean start from Google Assistant Simulator

问题

I am still quite new to this topic, so sorry if I didn't provide enough information.

For the first time, I copoed everything from https://developers.google.com/actions/dialogflow/first-app to learn about it, which works great.

After, I tried to create my own one, then at the end, I got this message "My test app isn't responding right now. Try again soon." from https://console.actions.google.com/project/[[PROJECT-ID]]/simulator/.

Therefore, I tried to delete everything and make a complete new start, including all the projects on https://console.actions.google.com/ and https://console.dialogflow.com.

I then copied the exact same thing from https://developers.google.com/actions/dialogflow/first-app again, but this time, I still got "My test app isn't responding right now. Try again soon." from https://console.actions.google.com/project/[[PROJECT-ID]]/simulator/.

• I tried to look at firebase log, no error indeed
• I tried to use the web demo from the integration tab, everything works (which means the server side code or the connection have no problem) as expected, firebase also logged the request.
• I tried to use a different browser (chrome -> firefox) still not working.

Here is the response code from the Google Assistant Simulator (its kinda nothing):

{
  "audioResponse": "//NExAARqQ...",
  "conversationToken": "GidzaW11bG...",
  "response": "My test app isn't responding right now. Try again soon.",
  "visualResponse": {
    "visualElements": []
  }
}

And here is the debug message (yes, its nothing in there, so I'm stuck):

{
  "agentToAssistantDebug": {},
  "assistantToAgentDebug": {}
}

Any help would be appreciated. Thanks!

Make sure your Actions on Google project has a name.

I spent almost 2 days scratching my head on this. Just go to Activity controls of the relevant google account (The account that you are using for the simulator) and turn on all those switches (You may leave out Youtube related stuff).

And.....Voila, it works!

Usually, these are turned off for non-personal accounts.

Faced the same issue when I tried to change the language of app to a locale.

Try the following,

• Check if the welcome intent and fallback intents have responses and training phrases

• All contexts are mapped

• Disable and enable testing

I had the exact same issue and after struggling for hours I found the stupid error on my side: In my Dialogflow Agent settings, I accidentally turned on the V2 API. So my firebase function kept complaining about null intent. Hope this help.
