The customizer import file is not in a correct format.

Hello,

i’m using a “One Click Demo Importer” plugin to import demo site.

but i can’t properly import files while i using local import files (from theme folder)?

See below code:

<?php
function thme_import_files() {
  return array(
    array(
      'import_file_name'             => 'Demo Import 1',
      'local_import_file'            => trailingslashit( get_template_directory() ) . 'inc/eocdi/demo-content.xml',
      'local_import_widget_file'     => trailingslashit( get_template_directory() ) . 'inc/eocdi/widgets.json',
      'local_import_customizer_file' => trailingslashit( get_template_directory() ) . 'inc/eocdi/customizer.dat',
      'import_preview_image_url'     => trailingslashit( get_template_directory() ) . 'screenshot.png',
      'import_notice'                => __( 'Save time by import our demo data, your website will be set up and ready to customize in minutes.', 'text-domian' ),
      'preview_url'                  => 'https://www.demo.webhuntinfotech.com/themename',
    ),
  );
}
add_filter( 'pt-ocdi/import_files', 'thme_import_files' );
function thme_after_import_setup() {
    // Assign front page and posts page (blog page).
    $front_page_id = get_page_by_title( 'Home' );
    $blog_page_id  = get_page_by_title( 'Blog' );

    update_option( 'show_on_front', 'page' );
    update_option( 'page_on_front', $front_page_id->ID );
    update_option( 'page_for_posts', $blog_page_id->ID );
	
	// Assign menus to their locations.
    $main_menu = get_term_by( 'name', 'Primary Menu', 'nav_menu' );
    $top_menu = get_term_by( 'name', 'Top Menu', 'nav_menu' );
    set_theme_mod( 'nav_menu_locations', array(
			'primary' => $main_menu->term_id,
			'top' => $top_menu->term_id,
		)
    );
}
add_action( 'pt-ocdi/after_import', 'thme_after_import_setup' ); ?>
