Prestashop 9 with Docker - Cannot connect with the DB

[Ceestos]

Hi, I'm trying to create a Prestashop container with Docker

But when I'm reaching the DB page to connect, an error appear.

At the beginning, I was thinking Prestashop ignore my `environment` variables, but I try to connect manually to the db and it work with

`DB_USER:user` and `DB_PASSWORD:password`

Databases Exists :

But nothing seem to work

Someone can help me ?

docker-compose.yml
