If you're refunding a customer's charge, the amount should go to their payment method

Your code looks a bit strange though

Are you doing direct charges or destination charges?

When Im creating a paymentIntent I do a "transfer_data" to the connected account. I thing I use destination charges.
why my refund code is strange ?

[ruby gulch]

If you're using destination charges, you shouldn't need to pass stripe account header

Only reverse_transfer and the charge id on the platform
