Hi i am trying to make a manifest.json file which has chrome.cookies permissions which i think is an api.

i tried to upload this code

{
    "manifest_version" : 2,
    "name" : "coding train extension",
    "version" : "0.001",
    "host_permissions":[
        "*://*.google.com"
    ],
    "permissions":[
        "cookies"
    ],
    "content_scripts":  [
        {
            "matches": [
                "<all_urls>"
            ],
            "js": ["content.js"]
        }
    ]
}

The code loaded successfully but got an error

what am i doing wrong?
