Firebase sending notification Not working in laravel

I’m using Laravel version 7.0.1.
Accidently My push notification service with Laravel is not working without any changes in my code and Firebase settings.

Here I provided my function of sending push notification and also mentioned the error.

It will be great if anyone can help me out.

This is my Laravel version 7.0.1 ‘s Code

function sendNotification($data)
    {
        $url = 'https://fcm.googleapis.com/fcm/send';

        $serverKey = getenv('FIREBASE_SERVERKEY');

        $encodedData = json_encode($data);
        $headers = [
            'Authorization:key=' . $serverKey,
            'Content-Type: application/json',
        ];

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
        curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
        // Disabling SSL Certificate support temporarly
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $encodedData);
        // Execute post
        $result = curl_exec($ch);
        if ($result === FALSE) {
            die('Curl failed: ' . curl_error($ch));
        }
        // Close connection
        curl_close($ch);

        // Decode the result
    $response = json_decode($result, true);

    // Check for errors in the FCM response
    if (isset($response['error'])) {
        die('FCM error: ' . $response['error']);
    }

    // Optionally, print the entire response for debugging
    dd($response);
        return true;
    }

**And I’m getting this error.
