Ah, it’s possible that the old container was cleaned up when you ran `launcher cleanup` (since it wasn’t running).

Ok, can you try editing your `app.yml` file, and add this under the `env` section. Make sure the indentation is the same as all the other variables in that section.

```plaintext
DONT_PRECOMPILE_CSS: 1

```

Then try rebuilding again.
