I’m running into the same problem. To make sure there are no issues related to our own I just tried a vanilla setup of https://github.com/openanalytics/shinyproxy-config-examples/tree/master/02-containerized-docker-engine. These steps reproduce after retrieving Dockerfile and application.yml from above github link. I removed authentication to exclude that as a possible cause as well.
docker network create sp-example-net
docker build . -t shinyproxy-example
docker pull openanalytics/shinyproxy-demo
docker run -d -v /var/run/docker.sock:/var/run/docker.sock --net sp-example-net -p 8080:8080 shinyproxy-example
ShinyProxy loads, opening the Hello World app retrieves a containerPath. However, the resulting GET /endpooint/{UUID} returns a 500. The full shinyproxy.log from start and opening the helloworld app is added below. Any pointers on how this can be resolved would be greatly appreciated.
