Stripe subscription checkout form says "Oops! Subscription plan does not exist" after submitting.

Hello, I am having trouble with Stripe on my JotForms.  When I fill out every field of my form then press Submit, I am getting an "Oops! Subscription plan does not exist" error (screenshot attached).  I have integrated with Stripe properly and setup my subscription plan with JotForm. The error happens on both my website and on the JotForm preview. Why is this happening?

I checked your form and I was able to replicate this issue.

Also, I noticed that the Stripe integration is in Test mode. Would you mind testing it by switching the integration to Live mode:

Let us know how it worked.

Thank you!

The problem originally happened on live mode. We switched it to test mode to try to troubleshoot it and are getting the same error.

I'm trying to suspect that this is happening to your specific form, which includes those that being cloned by it, as I was not able to replicate the problem on a different form integrated with Stripe and uses subscription payment. But I was able to replicate on your form, and on a cloned form. With this, I would like to recommend to start a fresh blank form and create your fields there. 

We'd love to hear your updates on this case.

Thanks.

We ended up just remaking the form and the Stripe integration worked again.  Not sure what caused the original error, but thank you!
