Internal server error when accessing odoo running in docker

If you're setting up Odoo in Docker for the first time and hit an "Internal Server Error" when visiting http://localhost:8069, don’t panic — your setup might actually be fine.

This issue usually happens because:

🔄 Odoo needs a few moments to initialize the database on first launch.

When Docker starts Odoo, it begins creating:

• The PostgreSQL database
• Default admin user
• Addon metadata
• Web assets

This takes 15–60 seconds depending on your system. If you hit the browser too soon, the server isn’t ready and throws an error. Wait 30–60 seconds after docker-compose up -d before opening the browser and visiting http://localhost:8069
