Debugbar messages not working

[cosmy81]

HI, I have the debugbar working on my site, but the messages are not working.
The debugbar inizialization is:
(new Snowair\Debugbar\ServiceProvider(BASE_PATH . '/config/debugbar.php'))->start();
Then if I try to use it, nothing happens:

<?php
          $debugbar=$di->get('debugbar');
          $debugbar->startMeasure('start-1','how long');        // startMeasure($internal_sign_use_to_stop_measure, $label)
          $debugbar->addMeasurePoint('start');                  // measure the spent time from latest measurepoint to now.
          $debugbar->addMessage('this is a message', 'label');  // add a message using a custom label.
          $debugbar->info(ENVIRONMENT,SITENAME);  // add many messages once a time. See PSR-3 for other methods name.(debug,notice,warning,error,...)
          $debugbar->addMessageIfTrue('1 == "1"', 1=='1','custom_label'); // add message only when the second parameter is true
          $debugbar->addMessageIfTrue('will not show', 1=='0');
          $debugbar->addMessageIfFalse('1 != "0" ', 1=='0');       // add message only when the second parameter is false
          $debugbar->addMessageIfNull('condition is null', Null ); // add message only when the second parameter is NULL
          $condition='';
          $debugbar->addMessageIfEmpty('condition is emtpy', $condition ); // add message only when the second parameter is empty
          $debugbar->addMessageIfNotEmpty('condition is not emtpy', $condition=[1] ); // add message only when the second parameter is not empty
          $debugbar->addException(new \Exception('oh , error'));
          $debugbar->addMeasurePoint('stop');
          $debugbar->stopMeasure('start-1');                    // stopMeasure($internal_sign_use_to_stop_measure)

If I try inside volt template I receive an error:
{{ addMessage('test message','label') }}

Macro 'addMessage' does not exist

1. enable the "view" collector
2. delete all files in the "cache/volt" directory

then retry.
