Unable to generate api key if the variables are in the docker compose file

[alpap]

In the compose file the environment variables are defined and it seems to work but when i try to generate the the app key using

docker exec -it servas php artisan key:generate --force

I get the following error

In KeyGenerateCommand.php line 100:
