result.credit_card_verification is returning nil e

Question

I'm using braintree for payment processing and I'm trying to get Processor Response Codes from Braintree with Ruby.

Here is my code :

 verification = result.credit_card_verification
 response_code = verification.try(:processor_response_code)

I'm getting verification as nil even when there is error.

Is there something else to get Processor Response Codes?

I got this code from here

Here is my result.erros :

:errors: !ruby/object:Braintree::Errors
  errors: !ruby/object:Braintree::ValidationErrorCollection
    errors: []
    nested:
      :customer: !ruby/object:Braintree::ValidationErrorCollection
        errors: []
        nested:

_{I work at Braintree. If you'd like more help than you can get here on Stack Overflow, please reach out to our support team.}

Handling Braintree result objects is progressive.

If result.success? is false, then you check for result.errors, which represent validation errors.

If result.errors is nil, then the request was valid. In this case, you will have a transaction or verification object just as if result.success? was true.

You can then look at the result.verification's status, processor_response_code, gateway_rejection_reason, etc.

The linked documentation provides more details on handling error results.
