Describe the bug
When retrying a failed ACH payment, a raw variable dump appears in the customer error message. This issue occurs in both the Blocks and Shortcode checkouts.

To Reproduce
Steps to reproduce the behavior:

1. Attempt to pay with ACH using the test account 000777777771 and routing number 110000000. The payment should fail.
2. Without refreshing the page, retry the payment using the account 000000000009 and routing number 110000000.
3. Observe that the error message includes a raw variable dump.

Note: These test accounts are from Stripe’s documentation: Testing ACH.

Expected behavior
On the second attempt, the payment should be processed successfully without displaying a raw variable dump in the error message.
If an error message is displayed, it must be useful for the shopper.
