The issue is that recent updates to Power BI has caused validation to JSON files to be enabled. This has been raised with the Power BI Team.

For some reason, the previous method of converting PNG to Base 64 and including them in your JSON file for the purposes of conditional formatting, is no longer working. 

I suspect we need to convert the icons function to an array, a bit like how the primary colours are stored, as shown in the example below.

 

{
   "name":"Theme New",
   "dataColors":[
      "#26272A",
      "#00F96C",
      "#747474",
      "#28292C",
      "#00FFE0",
      "#A7A9AD"
   ],
   "icons":{
      "Mac":{
   "description":"MacOS Icon",
   "url":"image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAEAA..........."
      }

 

 
I'm still trying to figure this out, as the above worked perfectly until two PBI Versions ago. Will reply here if I figure it out.

Just know you're not alone.

Try with this simple structure, it works!
Thank you for the input but i have still the problem to name it and add more than one.
Can you help me?

{ "name": "Custom Theme", "icons": [{ "url":"data:image/png;base64,..................." }] }

Yep, that did the trick! And with multiple icons, this is the structure:

 

{
   "name":"Theme New",
   "dataColors":[
      "#26272A",
      "#00F96C",
      "#747474"
   ],
   "foreground":"#25272A",
   "background":"#FFFFFF",
   "tableAccent":"#F34FFF",
   "bad":"#ea1d13",
   "neutral":"#fdda00",
   "good":"#103a4c",
   "icons":[
      {
         "description":"macOS",
         "url":"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAEAAAABACAYAAAC....."
      },
      {
         "description":"Win",
         "url":"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAEAAAABACAYAAACq....."
      },
      {
         "description":"iOS",
         "url":"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAEAAAABACAYAAACq....."
      }
   ]
}

 

 

Icons seem to now appear at the top of the conditional formatting icons, instead of the bottom. 

Thanks mate.

I find the solution, see below in the post. You have to add the "description" attribute to name it! Thank you for the support!

Try this: 

let
Source = Json.Document(File.Contents("[FILE LOCATION]\new.json")),
#"Converted to Table" = Table.FromRecords({Source}),
#"Expanded icons" = Table.ExpandRecordColumn(#"Converted to Table", "icons", {"radiogrey", "radiogreen", "radioorange", "radiored"}, {"icons.radiogrey", "icons.radiogreen", "icons.radioorange", "icons.radiored"}),
#"Expanded icons.radiogrey" = Table.ExpandRecordColumn(#"Expanded icons", "icons.radiogrey", {"descripcion", "url"}, {"icons.radiogrey.descripcion", "icons.radiogrey.url"}),
#"Expanded icons.radiogreen" = Table.ExpandRecordColumn(#"Expanded icons.radiogrey", "icons.radiogreen", {"descripcion", "url"}, {"icons.radiogreen.descripcion", "icons.radiogreen.url"}),
#"Expanded icons.radioorange" = Table.ExpandRecordColumn(#"Expanded icons.radiogreen", "icons.radioorange", {"descripcion", "url"}, {"icons.radioorange.descripcion", "icons.radioorange.url"}),
#"Expanded icons.radiored" = Table.ExpandRecordColumn(#"Expanded icons.radioorange", "icons.radiored", {"descripcion", "url"}, {"icons.radiored.descripcion", "icons.radiored.url"}),
#"Changed Type" = Table.TransformColumnTypes(#"Expanded icons.radiored",{{"name", type text}, {"icons.radiogrey.descripcion", type text}, {"icons.radiogrey.url", type text}, {"icons.radiogreen.descripcion", type text}, {"icons.radiogreen.url", type text}, {"icons.radioorange.descripcion", type text}, {"icons.radioorange.url", type text}, {"icons.radiored.descripcion", type text}, {"icons.radiored.url", type text}})
in
#"Changed Type"

Thank you for the answer but i don't have a repository to put the file in when i publish on PowerBi service. So i have to use only the code. But in this way you describe how can i put the image in the conditional formatting? Thanks for the help
