Hello David,

It seems that session has been successfully created, I provide price id, it goes to the checkout website, but it does not show/fetch the subscription panel, only a very thin form for the card. The page is almost empty... I use .env file for encryption. Still I get the following error: 

Uncaught (in promise) IntegrationError: Invalid value for stripe.confirmCardPayment intent secret: value should be a client secret of the form ${id}_secret_${secret}. You specified: cs_test_b1yKo6ziMTc7Yy2yQOvFx0ERR6rDK9qo38O0ZBBxntKrOMtjbIEQunawW0_secret_fidwbEhqYWAnPydgaGdgYWFgYScpJ2lkfGpwcVF8dWAnPydocGlxbFpscWBoJyknd2BhbHdgZnFKa0ZqaHVpYHFsamsnPydkaXJkfHYneCUl.
