Description

Symfony throws Unsupported Connection: "session.handler.native_file" if you set handler_id in config/packages/framework.yaml to session.handler.native_file via .env variable.

I want to have the ability to switch between different session handlers in my application, so I added a .env variable named "SESSION_HANDLER" to set handler_id in framework.yaml. I want to support several session handlers, including native_file.

If I set a Redis URL in my SESSION_HANDLER .env var, it works perfectly and uses my Redis node as the session handler. But, if I set SESSION_HANDLER to session.handler.native_file, I got:

InvalidArgumentException

Unsupported Connection: "session.handler.native_file".

In vendor/symfony/http-foundation/Session/Storage/Handler/SessionHandlerFactory.php  (line 85) .

How to reproduce

Add SESSION_HANDLER var in .env and set it to session.handler.native_file:

.env:

SESSION_HANDLER=session.handler.native_file

Set handler_id via .env var in framework.yaml:

config/packages/framework.yaml:

framework:
    session:
        handler_id: '%env(SESSION_HANDLER)%'
