Json to Typescript generates empty file

[ak99372]

Using this json sample:

{
	"date": "2010-09-25",
	"Revenue": "65225000000.0",
	"Revenue Growth": "0.0",
	"Cost of Revenue": "39541000000.0",
	"Gross Profit": "25684000000.0",
	"R&D Expenses": "1782000000.0",
	"SG&A Expense": "5517000000.0",
	"Operating Expenses": "7299000000.0",
	"Operating Income": "18385000000.0",
	"Interest Expense": "0.0",
	"Income Tax Expense": "4527000000.0"
}

translates to blank typescript

// Generated by https://quicktype.io
//
// To change quicktype's target language, run command:
//
//   "Set quicktype target language"

if I remove some of the fields it eventually picks up but the json I'm working with has actually a lot more fields than this sample
