Pointing Pezzo's Local Proxy at the Local Server: A Two-Line Docker Compose Fix

A missing environment variable, and a default that pointed somewhere else.

简短回答

When Pezzo ran locally with Docker Compose, the proxy had no PEZZO_SERVER_URL, so its client fell back to the hosted default https://api.pezzo.ai. Requests reached the model provider, but the proxy logged "Invalid Pezzo Project ID" and nothing appeared in the local console. The fix sets the variable for the proxy service. It was merged as PR #355 and closed issue #299.

The fix

     env_file:
       - ./.env
       - ./apps/proxy/.env
+    environment:
+      - PEZZO_SERVER_URL=http://pezzo-server:3000

目标

Self-hosted setups should talk to themselves by default. Making that explicit in the Compose file removes a confusing first-run failure.
