have been trying to publish my shiny dashboard app on shinnyapps.io server. However, even though the app is working locally, I cannot seem to get any success in publishing it online. It gives me this error.

ERROR: An error has occurred. Check your logs or contact the app author for clarification.

I am running a Windows 10 64 bits machine.

If you are getting that error message it means you have successfully deployed your app to shinyapps.io but your app is not able to start, to help you with that, we are going to need more information, follow the advice in the error message and check the logs for your app.

The only thing in the logs that pops out to me is the error

Warning: namespace ‘DynNom’ is not available and has been replaced

Could you try the workflow suggested here, and see if you are then able to deploy?
