Issue description

Thanks for the great library!

I am using the Drop-In to accept credit cards and was testing cards from (https://developers.braintreepayments.com/guides/credit-cards/testing-go-live/php#card-numbers-for-unsuccessful-verification) to check for invalid cards.

In the sandbox account settings, I have enabled 'Card Verification' prior to storage in the Vault.

When using test cards '4000...1115' or '5105...5100' there is an error when trying to add a credit card.

Uncaught TypeError: Cannot read property 'creditCard' of null
    at p.t.exports [as _adapter] (hosted-fields-frame.min.html:1)
    at p.adaptResponseBody (hosted-fields-frame.min.html:1)
    at XMLHttpRequest.O.f.onreadystatechange (hosted-fields-frame.min.html:1)

This is cased as the post to https://payments.sandbox.braintree-api.com/graphql response returns

{
  "data" : {
    "tokenizeCreditCard" : null
  },
  "extensions" : {
    "requestId" : "..."
  }
}

This then leaves the UI in a locked 'loading' state. (see screenshot).

Can the Drop-In UI Handle verification of invalid cards?

Can you provide the request id so we can look up the request on our end?

I can't reproduce on my end. I get this view as I'd expect:

[jmannau]

Hi,
Here is a request id where it occurred

{
  "data" : {
    "tokenizeCreditCard" : null
  },
  "extensions" : {
    "requestId" : "be1da38e-84c9-430b-8675-ef0f9abd6f97"
  }
}

I was able to reproduce this. We'll work on getting it fixed. Thanks for the report!

@jmannau We have a fix for this in the pipeline, however if you want a quick fix, I believe you can just enable cvv or avs rules in your sandbox control panel: https://articles.braintreepayments.com/guides/fraud-tools/basic/avs-cvv-rules. Let us know if that helps.

Thanks Team. @alexgenco you beat me to it. Thanks for the work around. Out of curiosity, once fixed, will I need to update the drop-in library or is it a server fix?
Thanks very much for your quick response! :D

[crookedneighbor]

It's a fix that will happen on the server, so no need to upgrade.

The server side fix for this should be out. Let us know if there are any other issues.
