Stripe.process_stripe: Unable to cancel paymentIntent. The resource ID cannot be null or whitespace.

Hi, I'm getting a lot of these error messages, which I think arise from a hacking attempt this morning on a webform with a Stripe payment. It looks like these error messages arise every hour, with the Stripe cleanup job, and this is confirmed by there being around a hundred entries in civicrm_stripe_paymentintent table where the stripe_intent_id field is null. Can I simply delete the records with null fields in this table, or will that cause other issues?
