Hi,

Same bug here: Symfony 4 marks services as private by default, and Symfony 3.4 allow private services to be accessed with Container::get() but not Symfony 4.

So you can't get twig.loader.filesystem service now.

Can you show the stack trace for this exception?

Hello there, same issue here with SF4.1. ~~It seems the service twig.loader.filesystem existed between Symfony 2.0 to 2.6 and has been renamed since 2.7 to twig.loader.native_filesystem.~~

~~To me I don't see an issue to use the service name twig.loader.native_filesystem because in this package the requirement are:~~

"symfony/framework-bundle": "^2.7|^3.0|^4.0",

Edited

Thanks to @xabbuh the fix should be replacing method getDefinition() by findDefinition() to fix this issue.
