@Maciej Bialorucki How to solve MalformedResponse 'final_response' must be set. error in action simulator: am also having the same issue. — Vikram, Feb 09 '18 at 10:18
Are you using Dialogflow or the Action SDK? If Dialogflow, can you post a screenshot of the entire Intent that you think is handling it. If you're using a webhook - what JSON are you returning from the webhook or can you show the code that sends the reply? — Prisoner, Feb 09 '18 at 10:46
@Prisoner , yes am using Dialogflow. if (requestSource === googleAssistantRequest) { sendGoogleResponse(_DisplayName.toString()); } else { sendResponse(_DisplayName.toString()); } this is the code of webhook response. — Niranjan Dharmarajan, Feb 14 '18 at 06:33
Can you update the question with the code and with a screen shot of the Intent you think is handling your request? (Don't post code in comments since they're hard to read, but update the question and post a comment that you've done so.) — Prisoner, Feb 14 '18 at 10:02

There could be a silly mistake like I did.

In Your index.js file, Check out this similar line:

app.intent('favourite color', (conv, {color}) => {
    const luckyNumber = color.length;

In this, be sure that your intent name is exactly same as your intent that you created while creating a new intent.

NOTE: Intent name is CASE-SENSITIVE. So make sure you type the same name exactly in this line of .js file.

I had same issue, resolved following way

go to logs of firebase function in my case url was
https://console.firebase.google.com/project/project-1/functions/logs?search=&severity=DEBUG
Refresh action simulator window and Check error log while executing
In my case error was

I have added Intent handler in firebase function as below

app.intent('Default Welcome Intent', conv => { conv.ask('Hi, I am in welcom intent.') })
Refresh simulator window, and I got the proper response.

Similarly you can also find the cause of the error and resolve it.

Is this intent webhook enabled ?

if yes, did you catch this intent in your code

if no, did you add a response to your intent

That is usually the first 2 things to check

What I find is that you need something in Speech. In the Response I find

'Failed to parse Dialogflow response into AppResponse because of empty speech response'

I find Media Object works but not list or carousel as they don't have a Speech option. I am also trying to solve this problem.

If there is a way for List of Carousel to return a Speech response that might solve it

If anyone else have this issue try turning on "Enable webhook call for this intent" in Fulfillment under Intents .

I had similar issue and changing version(at Agent) resolved the issue:

consider using legacy Apis

Also you may need to provide a default response in the intent :

Check if you have multiple languages set in Dialogflow, if there is more than 1 language, and you have not added translations, it will come up with that message.
