Hi, @amansilla, looks like you did not configure Braintree payment method in Magento admin panel. Did you specify Merchant ID, Public Key and Private Key for Braintree?

[amansilla]

Hi @joni-jones thanks for your quick feedback. Yes, for sure I provided the ´Merchant ID´, ´Public Key´ and ´Private Key´. I'm guessing that JS is not be able to get the clientToken because I'm running it in a VM and Braintreee maybe check the domain name doing the request.

I'll report the result of my test asap.

You can also use xdebug to check if getClientToken method returns token.

[amansilla]

Yes, I did it and getClientToken return always null. I'm still researching it why right now but I guess it's a bug.

The \Magento\Braintree\Model\Adapter\BraintreeAdapter::generate returns null if token generation fails with exception. In this method you can find original reason of failing, please, post this exception message with stack trace.

[amansilla]

I know but take a look here that the generate is called without params. https://github.com/magento/magento2/blob/2.1.2/app/code/Magento/Braintree/Model/Ui/ConfigProvider.php#L116 😄

So? In 2.1.2 version token generation does not use merchant account id (this param added in 2.1.3 version), but it anyway token will be generated without any params.

[amansilla]

In my case and it's important with production credentials it's not being generated. Why? I've no clue.

Did you try to set breakpoint in BrainteeAdapter::generate?

[amansilla]

I debugged the BrainteeAdapter::generate and there during ClientToken::generate a exception will be thrown since a 401 HTTP status is returned back when doing the POST request .
