In Trailhead Deploy Agent Authentication Project ,task 3

I follwed according the project instructions, like activated the flows, created variables and applied filters.  but when run the prompt for the email  ''Will.Johnson@run.com''

the ''send email with verification code'' flow action in canvas should bring me the details like below:

{!customerType} = "Contact"

{!customerId} = "003d200000R5MIzAAN"

{!authenticationKey} = "3a0fe2b8e2f0440883ef85effc2a0751b5415a2c64cc4a319fcb11bb74d515391749354058"

{!verificationMessage} = "If you have provided a valid email or username, you should receive a verification code to verify your identity. Please enter the code"

{!verificationCode} = "270750" 

 but out put shows like this  below 

{ 

  "customerType": null, 

  "customerId": null, 

  "authenticationKey": null, 

  "verificationMessage": "If you have provided a valid email or username, you should receive a verification code to verify your identity. Please enter the code", 

  "verificationCode": null 

}. 

I debug the flow 'send email with verification code" with the email it give the results like in the picture or above ''correct out put'' 

Help me out what I am missing?
