ShinyProxy: java.lang.reflect.InvocationTargetException: null - shiny

Question

I have a .Rmd along with a .sql file that is read by the .Rmd file that I’m trying to deploy in ShinyProxy. I am able to run this from within RStudio on my Mac.
The application loads, I can see it in ShinyProxy, but when I click on the application, it launches, then says please wait, then the error java.lang.StackOverflowError. I tried increasing the stack size with the JAVA_OPTS in the Dockerfile.
I do see this in shinyproxy.log:
