Hello,

You have private networking disabled for this project and that is why that variable is empty, since its a private hostname.

Go into any one of your services and enable private networking.

Hey, few more questions . in dev mode how i can access database services using public url or host . becuase using private host i can't connect my databse with pgadmin4. if their is any way to access them in dev mode on my localmachine or i have to set the public url in env.Thanks

You can access it using the public URL. If you're having connection issues over the public network, check and ensure that you're supplying the correct params (host, port, username, password).

okay thanks
