	);
	$posts = get_posts( $args );

	foreach($posts as $post){ setup_postdata($post);
    	$postid = $post->ID;

    	if (have_rows('content_blocks', $postid)) {

    		$field_key = "field_558bf9c9a9492";
    		//$components_value=[];
    		//$components_value=array();
    		$components_value = get_field($field_key, $postid);

    			// get layout
				$layout = get_row_layout();

				if( $layout === 'story_text' ) {
					
					$story_text_title = get_sub_field('title');
					$story_text_subtitle = get_sub_field('subtitle');
					$story_text_content = get_sub_field('content');
					
					$acf_fc_layout = "text";

					$array_text_layout_values = array(

						'subtitle' => $story_text_subtitle,
						'content'  => $story_text_content

					$components_value[] = $array_text_layout_values;
					//array_push($components_value, $array_text_layout_values);

				} elseif( $layout === "story_image" ) {
			
					$story_image_caption = get_sub_field('caption');
					$story_image_subcaption = get_sub_field('subcaption');
					$story_image_image = get_sub_field('image');
					$story_image_portrait = get_sub_field('portrait');

					$acf_fc_layout = "image";
					$array_image_layout_values = array(
						"acf_fc_layout" => $acf_fc_layout,
						'caption'    => $story_image_caption,
						'subcaption' => $story_image_subcaption,
						'image'  => $story_image_image,
						'format' => $story_image_format
					);
					$components_value[] = $array_image_layout_values;
					//array_push($components_value, $array_image_layout_values);
				
				}

    		endwhile;

		}
		if (!empty($components_value)) {
			update_field( $field_key, $components_value, $postid );

You need to use the field key for the flexible content field and all of the sub fields when adding content to a post for the first time.
