I am a beginner to opencpu service and I want to deploy my app on opencpu public server. I tried using GitHub webhook to deploy my app as the opencpu guide says on their website. According to opencpu after pushing R package code to GitHub and configuring webhook the app will be deployed on their server and can be used using http://yourname.ocpu.io/ but in my case, I didn't find my app on the URL
"Github App sdiwash/hello not installed on this server"
and got this message.
