AMP pages & missing author

Hello, structured data testing tool is saying “missing author” for my AMP pages. I use “Schema” plugin to markup AMP pages, and this is the file for the integration with AMP by Automattic plugin. May you be so gentle to tell me what to edit to remove the “missing author” error from AMP pages? Thanks in advance

<?php
/**
 * AMP plugin integration
 *
 *
 * plugin url: https://ww.wp.xz.cn/plugins/amp/
 * @since 1.3
 */
 
// Exit if accessed directly
if ( ! defined( 'ABSPATH' ) ) exit;

add_filter('amp_post_template_metadata', 'schema_wp_amp');
/**
 * Override schema json-ld for AMP plugin
 *
 * @since 1.3
 * @return schema json-ld final output
 */
function schema_wp_amp( $jason_array ) {
	
	global $post;
	
	// Check if AMP plugin is active
	if ( ! defined( 'AMP__FILE__' ) ) return;
	
	// Check if AMP function exists
	if ( ! function_exists('is_amp_endpoint') ) return;
	
	// Check if an AMP version of a post is being viewed
	if ( is_amp_endpoint() && is_single() ) {
		$json = array();
		// Get ref of Schema type in post meta 
		// @since 1.5.3
		$ref = get_post_meta( $post->ID, '_schema_ref', true );
		if ( $ref != '' ) {
			$schema_type 		= get_post_meta( (int)$ref, '_schema_type', true );
			$schema_sub_type 	= get_post_meta( (int)$ref, '_schema_article_type', true );
			$type = ($schema_sub_type != '') ? $schema_sub_type : $schema_type;
			$json = schema_wp_get_schema_json( $type );
			return $json;
		}
	}
	
	// Return the un-filtered array
	return $jason_array;
}
