WordPress uploaing blob file

Question

I tried two methods for uploading blob files to WordPress media library.

In first method i tried move blob tmp file to WordPress upload directory with move_uploaded_file(). Then tried upload this temp file with media_handle_sideload() function.

It is blob file that i sent via ajax:

array(
    'name'     => '2021-03-26_02-58-09',
    'type'     => 'image/png',
    'tmp_name' => 'C:\Users\me\AppData\Local\Temp\php28D8.tmp',
    'error'    => 0,
    'size'     => 1880058,
);

Ajax process:

$file       = $_FILES['file'];
$upload_dir = wp_upload_dir();

move_uploaded_file( $file['tmp_name'], $upload_dir['path'] . '/' . $file['name'] );

$url = $upload_dir['url'] . '/' . $file['name'];
$tmp = download_url( $url );

$file_array = array(
    'name'     => basename( $url ),
    'tmp_name' => $tmp,
);

$id = media_handle_sideload( $file_array, 0 );

var_dump( $id );

But it returns Sorry, this file type is not permitted for security reasons error.

So i tried this with wp_insert_attachment() function. It is uploading file but without image extension (.jpg, .png) and it is not generating additional image sizes. Here is what i tried:

$file       = $_FILES['file'];
$upload_dir = wp_upload_dir();

move_uploaded_file( $file['tmp_name'], $upload_dir['path'] . '/' . $file['name'] );

$id = wp_insert_attachment(
    array(
        'guid'           => $upload_dir['path'] . '/' . $file['name'],
        'post_mime_type' => $file['type'],
        'post_title'     => preg_replace( '/\.[^.]+$/', '', $file['name'] ),
        'post_content'   => '',
        'post_status'    => 'inherit',
    ),
    $upload_dir['path'] . '/' . $file['name']
);

var_dump( $id );
