I don't know where came wrong. The chrome extension keep on showing error

manifest.json

{
"name": "CatExtension",
"description": "Coding train practice-communication between background script and content script",
"version": "1.0",
"manifest_version": 3,
"action": {
    "default_popup": "popup.html",
    "default_icon": {
        "16": "/images/cat.png"
    }
},
"background": {
    "service_worker": "background.js"
},
"content_scripts": [
    {
        "matches": [
            "<all_urls>"
        ],
        "js": [
            "content.js"
        ]
    }
]

}

background,js

chrome.action.onClicked.addListener(buttonClicked);

function buttonClicked(tab) {
    console.log(tab);
}

It shows error

Where is the error?
