Not handling responses with errors: null

[stukennedy]

Any response with errors = null causes the library to throw an error

e.g. this response:

{
	"data": {
		"viewer": {
			"accounts": [
				{
					"r2OperationsAdaptiveGroups": [
						{
							"dimensions": {
								"actionType": "GetObject"
							},
							"sum": {
								"responseBytes": 87658765
							}
						}
					]
				}
			]
		}
	},
	"errors": null
}

throws
Error: Invalid execution result: errors is not plain object OR array

The library should be able to handle null errors i.e. the success state.
This is a Cloudflare API I'm calling, so obviously can't change the responses.
