No shiny application exists

I have followed instructions as outlined [here](https://cran.r-project.org/web/packages/RInno/vignettes/cont-installation.html) in order to create a continuously installing app. [This](https://github.com/oganm/import5eChar) package has the shiny app in it's [`inst/app`](https://github.com/oganm/import5eChar/tree/master/inst/app) directory. I have created a [release ](https://github.com/oganm/import5eChar/releases ) with a tag that matches the version in the [DESCRIPTION](https://github.com/oganm/import5eChar/blob/master/DESCRIPTION) file.

I have run (full code [here](https://github.com/oganm/5eInteractiveSheet/blob/master/appBuilder.R#L46-L63))

```r
create_app(
app_name = "5eInteractiveSheetCI",
app_repo_url = "https://github.com/oganm/import5eChar",
pkgs = depends,
app_dir = 'sheetCI',include_R = TRUE
)
compile_iss()
```
In order to create the installer (`depends` is a vector of dependencies). Yet when I complete installation and try to run it, I get `No shiny application exists at path "/app"` error. Am I missing something obvious here?

A non-continuous installation version of the app works just fine.
