Error message after account linking success

Question

I am getting an agent error after account linking success message.

After the user completes the account linking process, the agents says that he doesn't understand what the user is saying (but the user hasn't said a word!).

Here's how I start the account linking process:

if (accessToken) {
    conv.ask(loggedMessage)
  } else {
    conv.ask(new SignIn())
    conv.close(loggedMessage)
  }
  agent.add(conv)

The function finishes with a 200 status code, but I get an error on the simulator:

"Desculpe, mas não compreendi" is Portuguese for "I am sorry, but I did not understand".

Is this happening because the mic stays open when I use conv.ask ? How can I solve this?

Thanks in advance!
