a network with name customer_staging_default exists but was not created for project "customer_staging"

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

Adding custom Javascript code to the Sulu Admin UI requires a rebuild of the administration interface frontend application. According to the Sulu docs, running the following command is enough:
