Error on package.json: Unexpected token " at 1:1

Question

I'm trying to add a package in the new Unity Package Manager. I modified my manifest.json to target a local package. I created a new package.json :

 {
     "name": "com.enthropia.modalmanager",
     "displayName": "Modal Manager",
     "version": "1.0.0",
     "unity": "2018.1",
     "description": "A simple modal manager which open modals with fade in background. \n- To improve runtime calculations modals are intantiated only on first time call\n- Only one modal can be open in the same time\n- Overridable Build method can help you to inject datas in modal\n- Can be easily used with UIController",
     "keywords": [
         "modal",
         "manager",
         "enthropia"
     ],
     "category": "Managers"
 }

The file is found but Unity send me this error:

Error with package details: The file [[MyPath]\ModalManager\package.json] is not valid JSON: Unexpected token '' at 1:1 { ^ UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

Any idea?

package.json need be saved as UTF-8 without BOM

Yep, that would be my first guess when that error happens. Since it complains about the line / column 1:1 it has to be the first character. So in almost all cases it's the invisible byte order mark that is added depending on the encoding of the text.

Open with notepad-> save as -> utf-8 (not utf-8 BOM)
