I am using large file upload aws s3 bucket in laravel but i am facing issue [duplicate]

I am using large file upload aws s3 bucket in laravel but i am facing issue “Your proposed upload is smaller than the minimum allowed size” filesize 9.8

public function testS3Link()
{
    $link = "http://localhost/instacon-web/public/videoUpload/sample10mb.mp4";
    $time = time();
    // Destination path on S3 bucket
    $s3FilePath = 'instameet/'.$time.".mp4";

    // Initialize S3 client
    $s3 = new S3Client([
        'version' => 'latest',
        'region' => 'ap-south-1', // Change this to your desired AWS region
        'credentials' => [
            'key' => 'AKIAEXAMPLE',
            'secret' => 'examplekey',
        ],
    ]);

    try {
        // Get file size using cURL
        $ch = curl_init($link);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_HEADER, true);
        curl_setopt($ch, CURLOPT_NOBODY, true);
        $data = curl_exec($ch);
        $fileSize = curl_getinfo($ch, CURLINFO_CONTENT_LENGTH_DOWNLOAD);
        curl_close($ch);

        // Determine the part size
        $partSize = 5 * 1024 * 1024; // 5 MB
        $partNumber = 1;
        
        // If the file size is smaller than the part size, upload it as a single part
        if ($fileSize <= $partSize) {
            $result = $s3->putObject([
                'Bucket' => 'instacon',
                'Key' => $s3FilePath,
                'Body' => fopen($link, 'rb'),
            ]);
            dd($s3FilePath);
        }
        
        // Initiate the multipart upload
        $result = $s3->createMultipartUpload([
            'Bucket' => 'instacon',
            'Key' => $s3FilePath,
        ]);

        // Get the upload ID
        $uploadId = $result['UploadId'];

        // Upload the parts of the file
        $file = fopen($link, 'rb');
        while (!feof($file)) {
            $part = fread($file, $partSize);
            $result = $s3->uploadPart([
                'Bucket' => 'instacon',
                'Key' => $s3FilePath,
                'UploadId' => $uploadId,
                'PartNumber' => $partNumber,
                'Body' => $part,
            ]);
            $parts[] = [
                'PartNumber' => $partNumber,
                'ETag' => $result['ETag'],
            ];
            $partNumber++;
        }
        fclose($file);

        // Complete the multipart upload
        $s3->completeMultipartUpload([
            'Bucket' => 'instacon',
            'Key' => $s3FilePath,
            'UploadId' => $uploadId,
            'MultipartUpload' => [
                'Parts' => $parts,
            ],
        ]);

        dd($s3FilePath);

    } catch (S3Exception $e) {
        // Handle exception
        echo $e->getMessage();
    }
}

the above code i have tried but its not working. Its return error Your proposed upload is smaller than the minimum allowed size. Can you suggest any solution.
