Stripe Payment element - null payment method - urgent

Our live payments are not being processed. In the webhook log, I see:

"payment_method": null,

and then

"payment_method_types": [
"card","klarna",
],"processing": null,"receipt_email": null,"review": null,"setup_future_usage": null,"shipping": null,"source": null,"statement_descriptor": null,"statement_descriptor_suffix": "Our Shop Name","status": "requires_payment_method","transfer_data": null,"transfer_group": null,

in the plugin config, whe set "Authorize and capture"

What could be happening?
