"Required object 'amount' is not provided." - Got this error by hitting the refund()

[viveknegi111]

Describe the bug
Got this error - response = { "status"=>422, "errorCode"=>"100", "message"=>"Required object 'amount' is not provided.",
"errorType"=>"validation" }
by hitting the AdyenClient.new.payments.refund(input1, input2)

How to reproduce
Steps to reproduce the behavior.
a) initializing first:
adyen_client = Adyen::Client.new.tap do |_adyen|
_adyen.api_key = "some value"
_adyen.env = :live
_adyen.live_url_prefix = "some value"
_adyen.checkout.version = 68
end
b) By hitting this adyen_client.payments.refund(input1, input2) where

input1 = {
  'amount': {
    'value': 456,
    'currency': "USD"
  },
  'reference': "some value1",
  'merchantAccount': "some value2"
}

input2 =   {"paymentPspReference": "some value3"}

I got the above mentioned error. Please check . Is something missing here from my end in passing parameters?

Expected behavior
No idea about the response as hitting the API gives error.
