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

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

• lifetime is now anintegerNode()
• 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 theintegerNode() changes (as you suggested).

@HeahDude am I mislooking something, or would reverting these 2 lines not result in much harm? (only a little less strict config processor)
