What steps will reproduce the problem?
(1) We're trying to update our existing packaged app on the Chrome Web Store with a hosted app. Our manifest file looks like this:
{
    "manifest_version": 2,
    "name": "Drawp for School",
    "version": "2.0.0",
    "app": {
        "launch": {
            "web_url": "https://app.drawpforschool.com/"
        }
    },
    "icons": {
        "128": "drawp-128.png",
        "144": "drawp-144.png"
    }
}
(2) Once the uploading process gets completed:
    An error occurred: Failed to process your item.

    Please specify background subsection of app section in the manifest.

What is the expected result?


What happens instead?
We get the following error once the uploading process gets completed:
    An error occurred: Failed to process your item.

    Please specify background subsection of app section in the manifest.
