I am having a very similar issue. This is the error message I get.
2015-06-22 20:54:28 – DEBUG –> GFPaymentAddOn::validation(): Authorization result for form #4 submission => Array
(
[error_message] => Must provide source or customer.
[is_success] =>
[is_authorized] =>
)
Anyone have any ideas? If I create a regular form it works perfectly. This only happens if I create a form with stripe payments.
