As @wouterj explained we cannot use env variables after #35910 merged.

> Hmm, so I'm guessing this is what happens:

> * `lifetime` is now an `integerNode()`
> * For the Config component (which IIRC doesn't know anything about env variables), you're passing a string: `"%env(int:REMEMBER_ME_COOKIE_LIFETIME)%"`
> * This throws an error, although if it wouldn't, the DI component would sucessfully process the string into a integer before it's used by any PHP class.
>
> So we either make Config aware of environment variables (that's probably a huge feature) or we revert the `integerNode()` changes (as you suggested).
