Comment 4 for bug 2057948

Thanks for working on this, Ken!

I've tested the patch with testing keys set up in the credit.processor.stripe.pubkey and credit.processor.stripe.secretkey library settings. Unfortunately, I'm getting an error when I attempt to pay a charge while logged into the opac:

We are unable to process credit card payments at this time. We apologize for the inconvenience. Please contact the library for further assistance.

Evergreen logs show the following:
