We have installed Shiny Server and RStudio Server on a CentOs 7. We can see the sample-apps that come pre-loaded into it (sample-apps/hello/), which run absolutely fine.
However, when we copy+paste these same server.R and ui.R files into a new folder (sample-apps/new_hello) and try to run this new version, we get the following error:
ERROR: An error has occurred. Check your logs or contact the app author for clarification.
We are also unable to run our own shiny apps which are already working on our own laptops. So it is not R-code related.
Are we missing a step here?
