I am trying to deploy my R application using ShinyProxy and docker. As soon as run the command, java -jar I get a nested exception in docker terminal stating Illegal argument exception. I am attaching the last traceback error. I referred https://www.databentobox.com/2019/11/05/deploy-r-app-with-shinyproxy/ tutorial for deploying R application. Any suggestion on how to overcome this error?
java -jar shinyproxy-2.3.0.jar
Caused by: java.lang.IllegalArgumentException: An HTTPS URI for DOCKER_HOST must be provided to use Docker client certificates

It worked for me by degrading shinyproxy version to 2.0.0 from 2.3.0.
