Package is invalid. Details: 'Could not decode image'

[pradeep bhutare]

Hello, I am trying to upload an extension to the chrome store and I am getting the following error message when I try to install the extension:

Package is invalid. Details: 'Could not decode image: 'Original_png.png''.

The unpacked version works.

But trying to download from the chrome store does not.

Please help! Thanks in advance!

Here is what my manifest.json looks like:

{

  "manifest_version": 2,

  "name": "AudioFont",

  "version": "1.1.0",

  "icons": {

   "16": "images/Original.png",

   "32": "images/Original.png"

},

  "browser_action": {

              "default_icon": "images/Original_png.png",

              "default_popup":"popup.html"

                },

    "background": {

      "scripts": ["js_jquery-3.2.1.min.js","background.js"],

      "persistent": true

  },

  "permissions": [

    "*://*/*",

    "tabs",

    "cookies",

    "activeTab"

  ]

}

One of my engineering colleagues lookef into this earlier today. It appears like the problem is that the asset Original_png.png (I believe that's the file name, I'm going from memory) is too large. Normally generating a CRX compresses some arrests, but it seems CWS isn't currently don't that.

You can see this first hand if you compare the asset inside the CRX file you get from the Web Store to a CRX file you manually create yourself in Chrome: the CWS version of the image will be 4k x 4x but the manually packaged one will 1k x 1k. 

I'll follow up with CWS in this tomorrow, but for the moment you should be able to work can work around this bug by shrinking the image before you publish.
