There should be a `version` key in your `app.yml` file.

```plaintext
  #version: tests-passed

```

Remove the `#` and change `test-passed` to the version you want to use; e.g. `v1.3.4`. [Tags · discourse/discourse · GitHub](https://github.com/discourse/discourse/tags) shows the available version strings.
