Hello!
I’m the same person as /u/appartmint - I just wasn’t allowed to post more than 3 comments, being a new account.
The issue has not resolved. Still getting the mysterious error any time I try to checkout a subscription with a checkout link.
I made a workaround using client.subscriptions.create with a client.orders.create in draft state. That sends my users an invoice for the subscription, and I kinda figured out how to determine if they’ve paid it. I don’t love the UX, not sure if checking whether or not they have a card on file is valid for making sure they’ve paid, and would love the issue fixed so they can just checkout without jumping through hoops.
