fetch issue with json from WP REST API custom endpoint

I try to fetch a JSON generated by the WP rest api.
based on an addapted version from exemple:
https://www.fusetools.com/examples/social-media-screen

my json look like this:

[
   {
      "Issue":"3143",
      "Count":1,
      "ID":16
   },
   {
      "Issue":"3144",
      "Count":9,
      "ID":15
   },
   {
      "Issue":"3145",
      "Count":5,
      "ID":14
   }
]

and I don’t have

{ "SomeName":

at the begining like in the example JSON:

{ "responseData":
	[
		{ 
			"author": "Hermione Robinson",

therefore, I didn’t find a way to access the data (as in the example) like so:

   <Each Items="{data.SomeName}">  <<<-- don't have `SomName`
     <Text Value="{Issue}" />
   </Each>

I did check that my json is valid,
and manage to fetch with jquery on my web version with:
$.getJSON(url...

any idea?..

If the array is the entire response object then you simply bind to that. E.g. <Each Items="{data.SomeName}">
