Exclude doesn’t work

I’ve tested excluded categories, and it doesn’t work as i see i’m always get Post Category as 1

PHP Code

			$s2_taxonomies = apply_filters( 's2_taxonomies', array( 'category' ) );
			$post_cats     = wp_get_post_categories($post->ID);
			// Fail gracefully if we have a post but no category assigned or a taxonomy error
			if ( is_wp_error( $post_cats ) || ( empty( $post_cats ) && 'post' === $post->post_type ) ) {
				return $post;
			}
			
			$wfile = fopen("log.txt", "a+");
			fclose($wfile);		
			$myfile = fopen("log.txt", "a+") or die("Unable to open file!");
			$date = new DateTime(null, new DateTimeZone('Europe/Vilnius'));
			$txt = $date->format('Y-m-d H:i:s');	
			$txt .= "\n--- POST INFO ----\n";	
			$txt .= print_r($post, true);			
			$txt .= "\n--- S2 Options ----\n";	
			$txt .= print_r($this->subscribe2_options, true);					

			$check = false;
			// is the current post assigned to any categories
			// which should not generate a notification email?
			$excludes = explode( ',', $this->subscribe2_options['exclude'] );
			$txt .= "\nPOST CATS \n";
			$txt .= print_r($post_cats, true);		
			$txt .= "\nEXCLUDED CATS \n";
			$txt .= print_r($excludes, true);					
			foreach ($excludes  as $cat ) {
				$txt .= "\n FOREACH AS excludes as cat \n";
				$txt .= "CAT ID:".$cat."\n";
				
				if ( in_array( (int) $cat, $post_cats, true ) ) {
					$check = true;
					$txt .= "\nIN EXCLUDE\n";
				} else {
					$txt .= "\nNOT IN EXCLUDE\n";
				}
			}	
			$txt .= "\n\n\n";
			fwrite($myfile, $txt);
			fclose($myfile);

I wrote some debug in log file
