You should make sure that you’re pulling the latest copy of `discourse_docker` in `/var/discourse` as well. The `./launcher rebuild` command used in the [standard install](https://meta.discourse.org/t/142537?silent=true) takes care of that automatically. But if you’re using a custom script, you’ll need to do it yourself.
