Bug report

• Uncaught (in promise) TypeError: Cannot read property 'toUpperCase' of null at app.js:93

Describe the bug

• Uncaught TypeError occuer when the product description is null.

To Reproduce

1. Create a product that no have description(optional) at Stripe.
2. Back to client index.html and proceed to subscription.

Expected behavior

• Success to subscription.

  Additional context

• Use optional chaining before "toUpperCase" or display alert or something when description is null.
• I'm not sure this issue is bug or not. Product description is optional at Stripe. But, looks like Stripe form also have same issue ignoring optional.

@qeema thanks for reporting this. You're spot on, description is optional and optional chaining would be a good way to prevent this error. Would you be up for opening a PR to fix this? No worries if not, then I can take.
