WooCommerce Custom shortode : Avoid problems with Elementor editor

I’m using the code below in my theme’s functions.php file to be able to output the Product SKU in various places all over my templates with [woo_sku] shortcode. While this works fine, I can’t access the template editor (Elementor) without uncommenting the function, as there is no product context in the template and the error prevents the editor from loading.

Is there a way to catch the error and return an empty value when not in a product context?

function display_woo_sku() {
    global $product;
    return $product->get_sku();
}
add_shortcode( 'woo_sku', 'display_woo_sku' );

    I tried the below code now, it appears to work (though Loic's code above seemed to make more sense, imho :)

    function display_woo_sku() { 
    if ( ! is_product() ) {
        return 'no SKU';
    }
    global $product; 
    return $product->get_sku(); 
    } 
add_shortcode( 'woo_sku', 'display_woo_sku' );

    Ah, @LoicTheAztec, there was just a typo in your solution: method_exists with an s:

    function display_woo_sku() {
    global $product;
    
    if( is_a( $product, 'WC_Product' ) && method_exists( $product, 'get_sku' ) ) {
        return $product->get_sku();
    } else {
        return  'no SKU';
    }
}
add_shortcode( 'woo_sku', 'display_woo_sku' );

    Thanx a lot!
