app_dev Exception: non-existent service

[Xendiadyon]

Hello, in a rather complex projekt (Contao 4.4.33 with Metamodels 2.1 and a lot of other extensions), I tried to access the Simfony Profiler via the app_dev.php

When opening the app_dev.php, a Contao-Error is triggered. Using the Simfony Profiler error trace, I can see the following exception: You have requested a non-existent service "maw.mcw.events.listener.initialize_system". in vendor/menatwork/contao-multicolumnwizard-bundle/legacy_layer/classmap/MultiColumnWizardHelper.php (line 132)

line 132 $helper = \System::getContainer()->get($serviceName); and $serviceName is (of course): $serviceName = 'maw.mcw.events.listener.initialize_system';

Probably, we have an extension "somewhere" which uses the TL_HOOK "initializeSystem". In general, this should be no problem. But somehow the execution of the initializeSystem Hook leads to an error. The reason why the $serviceName 'maw.mcw.events.listener.initialize_system' is not found is unclear to me. I suppose it is not an issue with the extension (whatever-it-is) which uses the Hook, but with MultiColumnWizard.

Could you please check if this service exists?

you add the MCW bundle at your composer.json?

see https://github.com/MetaModels/core/issues/1260

MCW bunde you found here https://github.com/menatwork/contao-multicolumnwizard-bundle

If so, did you clear the cache? The service got renamed for the bundle from maw.mcw.events.listener.initialize_system to menatwork.multicolumnwizard-bundle.events_listener.initialize_system

Clearing the cache (rm -rf var/cache/{prod,dev}) should fix this.

Thank you. Clearing the cache already did the job. 😉
