Why is this Python dictionary (Json) returning a syntax error?

Question

I am using the Hangouts Chat API to make a bot, but for some reason my formatted card is getting me a syntax error. This is the variable with the dictionary:

bot_message = {
        "hangouts": {
            "header": {
                "title": article["title"],
                "subtitle": article["author"],
                "imageUrl": artile["urlToImage"]
            },
            {
                "widgets" [{
                    "buttons": [{
                        "textButton": {
                            "text": "Open this article on " + article["source"]["name"],
                            "onClick": {
                                "openLink": {
                                    "url": article["url"]
                                }
                            }
                        }
                    }]
                }]
            }
        }        # error occurs here
    }

Basically, I get a syntax error saying the commented curly bracket is invalid syntax. Does anything not match up? There shouldn't be anything that doesn't match up, because VS Code (what I am using right now) automatically adds closing brackets. Does Python sometimes return random errors when the error is somewhere else (think as in Swift)?

Could someone point out the error?

"widgets" needs a colon after.

The object containing "widgets" is a value with no dictionary key, which makes no sense. The structure looks like this:

bot_message = {"hangouts": {...}, {"widgets": [...]}}

It needs to be:

bot_message = {"hangouts": {...}, "something": {"widgets": [...]}}

or:

bot_message = {"hangouts": {...}, "widgets": [...]}
