What's wrong with this query?

Here is my query

 Model::where('artist_token', $token)
            ->update([
                ['artist_token' => "000"],
                ['account_token' => "000"]
            ]
        );

And here is the error

SQLSTATE[42S22]: Column not found: 1054 Unknown column '0' in 'field list' (SQL: update `models` set `0` = {"artist_token":"000"}, `1` = {"account_token":"000"}, 

This query should update "artist_token" and "account_token" to "000" according to the docs.
