php - WordPress wp_nav_menu is not working in header and footer file in WordPress 5.6 version

Question

I have tried to display menu in header and footer file but I got below error.

Warning: implode(): Invalid arguments passed in C:xampphtdocsXXXwp-includesclass-walker-nav-menu.php on line 153

I used below code in footer and header file.

wp_nav_menu(
    array(
    'theme_location'  => 'footer',
    'menu_class'      => 'menu-wrapper',
    'container_class' => 'primary-menu-container',
    'items_wrap'      => '',
    'fallback_cb'     => false,
    )
);

I have also tried to simple way like

wp_nav_menu( array( 'theme_location' => 'header' ) );

But it's always showing waning in WordPress version 5.6.

Someone please help me how can i resolve this error.
