BotFramework-Composer: Card Action button is not working with hero card in facebook messenger

Bot info

• SDK Platform: .NET
• SDK Version: 3.0.10.
• Active Channels: WebChat, Facebook
• Deployment Environment: Azure App Service

Issue Description

• I created a HeroCard. It have a button (CardAction) to select the item. If the user clicks on the button (the button title should be “click me”), I expect the user to see the response of “click me” intent. After clicking on button in messenger it gives error like “Object Serialized to String. JObject instance expected”.
• In the emulator it works perfectly. but in messenger it is not getting value, it is getting title as text and giving the above mentioned error.

Code Example

# HeroCard
[HeroCard
  title = Lets Begin
  subtitle = Microsoft Bot Framework
  text = Build and connect intelligent bots to interact with your users naturally wherever they are, from text/sms to Skype, Slack,   Office 365 mail and other popular services.

  buttons = @{cardActionTemplate( 'imBack',  'click me', 'click me intent' )}
]
# cardActionTemplate( type,  title, value)
[CardAction
    Types = @{if(type == null, 'imBack', type)}
    Title = @{title}
    Value = @{value}
    Text = @{value}
]
