Why is this custom function not working on WordPress?

Question

I want to output the fields value of above meta from custom field and ads above post meta from ad inserter . Is there any syntax error or something else. I couldn't figure out. Can anyone help me with it.

/**
 * Single Post Title & Meta Order
 */
if ( ! function_exists( 'astra_get_single_post_title_meta' ) ) {

    function astra_get_single_post_title_meta() {

        // Single Post Title and Single Post Meta.
        do_action( 'astra_single_post_order_before' );

        ?>
        <div class="ast-single-post-order">
            <?php

            do_action( 'astra_single_post_title_before' );

            the_title(
                '<h1 class="entry-title" ' . astra_attr(
                    'article-title-blog-single',
                    array(
                        'class' => '',
                    )
                ) . '>',
                '</h1>'
            ); 

            do_action( 'astra_single_post_title_after' );

            if ( get_field( 'above_meta' ) ) {
                ?>
                <div class="astra-above-meta-single-post">
                    <?php the_field( 'above_meta' ); ?>
                </div>
                <?php
            }

            do_action( 'astra_single_post_meta_before' );

            // Display ad above post meta
            if ( function_exists( 'adinserter' ) ) {
                echo adinserter( 15 );
            }

            // Display post meta
            astra_post_meta();

            do_action( 'astra_single_post_meta_after' );

            ?>
        </div>
        <?php

        do_action( 'astra_single_post_order_after' );
    }
}
