Get user posts with custom WP_Query on author.php

Question

I try to show custom post list with WP_Query on author.php like this:

    <?php $args = array( 'post_type' => 'post', 'author' => 'get_queried_object_id()', 'posts_per_page' => 9 );
    $the_query = new WP_Query( $args );
    if ( $the_query->have_posts() ) :
    while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
        
<figure><a href="<?php the_permalink(); ?>"><img src="<?php if ( has_post_thumbnail() ) : the_post_thumbnail(); endif; ?>" alt="<?php the_title(); ?>"></a></figure>
<h5><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h5>

                
        <?php endwhile; wp_reset_postdata(); ?>
        
        <?php else : ?>
        <p><?php _e( 'No posts by this author' ); ?></p>
    <?php endif; ?>

It gives posts from all authors for some reason. I've tried different combinations of 'author' array element with no luck or some other errors/issues (like displaying only one post for example).

Please help to solve this issue.

Functions in single quotes will be interpret as string.
You just need to remove single quotes in your $args array.

$args = array( 
    'post_type' => 'post', 
    'author' => get_queried_object_id(), //remove single quotes here
    'posts_per_page' => 9 
);
