Curl Command via Zapier to Create Stripe Invoice with Params

问题

I'm attempting to create a Stripe Invoice using the Curl command in Zapier, but am getting a (400) Bad Request - "Invalid request (check your POST parameters): unable to parse JSON request body". The arguments i'm passing seem pretty straightforward so i'm not sure if i'm missing something or if i'm not formatting something correctly.
