Enable error_page 500 / 502 / 503 / 504 in Unit;

[Evgeniy-Bondarenko]

How enable custom page in UNIT error (php/pyhon applications)?

as in nginx:

  error_page 502 /502.html;
  error_page 503 /503.html;
  location = /502.html { root /var/www/; try_files $uri /502.html; }
  location = /503.html { root /var/www/; try_files $uri /503.html; }

Unfortunately, there's no way to overwrite error pages in Unit right now and you have to use external solution. This feature is in the TODO list.
