looks like API_BASE_URL and API_URL environment variables doesn't work

I trying to up docker-compose.yaml Looks like API_BASE_URL is hardcoded in frontent and can't be override from .env file

i create working copy

git clone https://github.com/BloopAI/bloop ./BloopAI/bloop
cd BloopAI/bloop
git checkout oss

and BloopAI/bloop/.env with

API_URL=http://<my-ip>:7878

run

docker compose build bloop-app
docker compose up -d

and see frontend application always try to use http://localhost:7878

did i miss something?
