StatusObservedOur team will look into this soon, verify the cause and try to fix it in an upcoming release.
Why it happens
The Compose file references VERDACCIO_PORT, but no value was provided during deployment. Docker Compose substitutes an empty value, producing an invalid port mapping (:<empty>). The obsolete version field is only a warning and is not the failure cause.
