Stripe Dynamic Buy Now buttons without shopping cart

In an attempt to follow the Stripe Tutorials below, as a test we created a shopping cart, added to a Data Store, passed the product_ID (offerID in our case) to an API that queries the offer details (id, title, currency, amount)

The last steps are to create a checkoutSession with Custom Reference using the above query, set an id value with the createCheckoutSession.id in it, and get the Go To Payment button to use the stripe1.checking on Click.

All works well, the datastore is filled, passes the offerID to the API which queries/selects the right offer, but the stipe.php throws an error:

PS I have re-uploaded the /stripe/folder and the /dmxConnectLib/modules/stripe.php from version 3.9.2

Any idea what could cause this error?
