Following our guide to set up Traefik, Docker, and Compose with multiple networks, I ran into a problem:

a network with name customer_staging_default exists but was not created for project "customer_staging"
Set `external: true` to use an existing network

network customer_staging_default was found but has incorrect label com.docker.compose.network set to "staging_default"
