CURL Statement with JSON yields Server Error

Question

--Updated with Stack Trace Error--

I'm struggling trying to get the following code to process correctly:

curl -v -u SD4FWFCF-ASD2-32FD-AF34-F34A4FA4CA34:CO0I0MM0-2349-OIJC-3409-234F098JJ3F4 -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{"email":"[email protected]","amountPaid":19.99,"systemName":"test-purchase","recipientPhoneNumber":"5558884321","senderPhoneNumber":"8005551234","deliveryDate":null,"paymentType":5,"scriptValues":[{"key":"fname","value":"john"},{"key":"lname","value":"doe"},{"key":"width","value":"medium"},{"key":"length","value":"large"},{"key":"city","value":"Fairbanks"},{"key":"state","value":"alaska"}]}' -k "https://api.example.com/processorder" -o output.html

Every time I run this, I receive a 500 Internal Server Error.

Here is an example of that error:

Server Error in '/' Application.

Sequence contains no elements

I've tried to alter the json, but I can't figure it out for the life of me.

There's no way to answer this question without knowing more about the methods. There is likely a call to an empty sequence as @Abe Meissler stated.
