eval()’d code error

I switched woocommerce single classic product editor to Guthenburg editor using the following snippet. Thank you very much is someone could help. There is nothing wrong when

/ enable gutenberg for woocommerce
function activate_gutenberg_product( $can_edit, $post_type ) {
if ( $post_type == 'product' ) {
$can_edit = true;
}
return $can_edit;
}
add_filter( 'use_block_editor_for_post_type', 'activate_gutenberg_product', 10, 2 );
// enable taxonomy fields for woocommerce with gutenberg on
function enable_taxonomy_rest( $args ) {
$args['show_in_rest'] = true;
return $args;
}
add_filter( 'woocommerce_taxonomy_args_product_cat', 'enable_taxonomy_rest' );
add_filter( 'woocommerce_taxonomy_args_product_tag', 'enable_taxonomy_rest' );
