I am developing an app using sharetribe but I am unable to complete my payments setup through share tribe it always gives me this error
The translation error is indeed one thing (and recommendations from ttbohemian are great!).
However to fix the root issue that you can't finalize your payment, you should probably review your Online payment setup in the "Payment system" tab of your Sharetribe Go admin panel. There, if you have setup Stripe according to the instructions at https://github.com/sharetribe/sharetribe#payments, you should be able to add your Stripe account keys. Online payments should then work smoothly!
Or maybe you have added your own payment gateway to your local installation?
