Shiny Server doesnt deploy app

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?

It was a library issue with RMySQL which was a leftover from a previous attempt - willduchateau
So, installing this library solved your problem??? - Mohammad
Just check that shiny-server has permission to the right folders and it should be solved. For my case, RMySQL was installed on a folder that shiny-server was not able to access - willduchateau

OK, here is my solution:

You should install all the R's libraries in the following folder:

"/usr/local/lib/R/site-library"

and then make sure that the user shiny has the permission to access it.

I hope it can help other users that still looking for a solution.
