Why do I get errors in guzzle, despite the fact that everything is fine with the curl?

Time:01-17

I have error with Guzzle 7 in PHP 8.2. If i do query by Postman or curl all okey, but i need use guzzle lib or analog php lib. My code:

$this->client = new Client([
    'base_uri' => 'https://fcm.googleapis.com/fcm/',
    'headers' => [
        'Authorization: key=' . *SERVER_KEY*,
        'Content-Type: application/json'
    ]
]);
$fields = [
    'to' => *USER_TOKEN*,
    'notification' => [
        'title' => 'Title',
        'body' => 'Body',
    ],
    'data' => [
        'icon' => *LOGO*,
        'click_action' => *LINK_TO_SITE*,
    ],
];
try {
    $response = $this->client->post('send', ['json' => $fields]);
    $result = json_decode($response->getBody()->getContents(), null, 512, JSON_THROW_ON_ERROR);
} catch (Exception $e) {
    var_dump($e->getMessage());exit;
}

Error:

The headers array should contain both keys and values, like shown in the documentation. Fix your code like this:

    'headers' => [
        'Authorization' => 'key=' . *SERVER_KEY*,
        'Content-Type' => 'application/json'
    ]
