Can we have an example for handling errors with Braintree payment?

[planetaska]

Our Braintree payments are working, but the issue is when a credit card is not valid, the Pay gem will throw a 500 error and we need a way to rescue this.

Here is the trace message:

It seems I can't rescue this behavior with a normal rescue like this:

begin
    charge = account.payment_processor.charge(subtotal)
    # the controller will stop right here after the 500 status
rescue ## tried different error types: Pay::Error, Pay::BratinTreeError
    ## this doesn't get run
end

Is there anyway we can recover from this error?

Can you provide the full stacktrace for the error? I only see one line in actionpack which isn't helpful to track down what happened.

[planetaska]

Sure! Here is the full trace:

The line in 'create' is charge = account.payment_processor.charge(subtotal).
I used one of the "Card numbers for unsuccessful verification" from Braintree doc to produce an unsuccessful verification.

Thanks! That's most likely a bug in Pay it looks like. Will take a look. 👍
