Why the hell circleci remove my .env file?

I’m trying to move to circleci, we have a symfony project and we do commit the “.env”, it contain all the default env variable of our project (like done here GitHub - symfony/demo: Symfony Demo Application).
I realize that when I do the “checkout” step circleci remove the “.env” file cloned from the project, why ?? This does not make any sense, the checkout process shouldn’t change any file of my project.

Their is nothing in the doc about this, can some help me ?

Here a screenshot of an ls -la command that show that circleci remove my .env file (screenshot of bitbucket vs screeshot of the ls inside the step)

did you check your .gitignore? Does the file show up in the GH web interface (vs. locally)?
