Forecast error when deploying shiny app in shinyapps.io

shinyappsio

#1

The app (app.r, there isn't an app.ui file) works fine locally (on my windows 10 machine, running R 3.4.0, Rstudio 1.1.456). When deploying an app to shinyappsio, I get this error and the deployment fails:

Error in dyn.load(file, DLLpath = DLLpath, ...) :

I appreciate any input on this error and any help deploying this app. Thanks!

This is likely due to a badly built fracdiff that has been cached. I removed it from the cache and hopefully things will work now.

You might be running appDependencies in the wrong directory?

Hi Josh,
Thank you for the quick reply. Unfortunately, I am still unable to deploy the app. A modal appears the reads: You content could not be published because of a problem on the server. More information may be available on the server's home page: https://api.shinyapps.io/
If the problem persists, contact the server's administrator (Error code: 504)

Below is what appears in Deploy on Rstudio:

Yes, poor timing. There was just short outage that we are investigating. Please try again.

Hi Josh,
I was able to deploy the app and it appears to work normally. Thank you for your help.
