hello,

I try to place order with my cc payment details.
i will get error message: “unable to place order, Please try again.”

View the debug log file we noticed below error message.
Issues is braintree responses.
Braintree\Error\Validation::__set_state(array(
’_attribute’ => ‘base’,
’_code’ => ‘91508’,
’_message’ => ‘Cannot determine payment method.’,
)),

we try to debug the issue.
and noticed one of the transaction data missing from our payment request to braintree gateway

payment_method_nonce = NULL

So how to resolve the problem, Please advice me.

It’s only a guess!
Maybe because a wrong and mistake typo in braitree module
open file below
https://github.com/magento/magento2/blob/develop/app/code/Magento/Braintree/Model/Ui/ConfigProvider.php#L63
and then fix it by changing getCctypesMapper to getCcTypesMapper
