Error on MaintenanceListener

[2b3ez]

Symfony 2.7

I got this error in profiler : Uncaught PHP Exception Lexik\Bundle\MaintenanceBundle\Exception\ServiceUnavailableException

Line concerned is 194 :
throw new ServiceUnavailableException();

I can't display a custom error 503

Hi guys.

This error means enabled maintenance mode.

LexikMaintenanceBundle/Exception/ServiceUnavailableException.php

Line 24 in 718a655

parent::__construct(503, $message, $previous, array(), $code);

So, it looks like expected behaviour.

I can't display a custom error 503

Did you try next to set custom 503 error page?
