Unable to capture payment, vague error

[KRens]

Using stripe_checkout, I'm getting following vague error. It doesn't really tell me what to look into next in order to get this solved.

Fatal error: Uncaught Payum\Core\Reply\HttpResponse in /home/bot/domains/domain.com/public_html/payum/vendor/payum/stripe/Payum/Stripe/Action/Api/ObtainTokenAction.php:90

Instead of using composer (this was breaking redirects) I download the entire zip file, but still I'm getting this error. Seems like fully broken.

@KRens Can you please add your config files here to create a reproducer? (E.G paste the contents of your capture.php, config.php etc in order to see the full config and reproduce the error).
