The processingFee is always null in sandbox environment

[mozakrah]

I'm using CheckoutApi
in the redirectUrl the order_id should be appended in the url

I'm getting the order then I'm trying to get the payment using it's ID

but the issue is that the processingFee is always null?

How can I get the processingFee in this case?
I need to get the net amount of money that will be transferred to the merchant's account.
