Shiny App not working on shinyapps.io but works locally

AdamCornell · June 17, 2021, 1:30pm

I have an error where when I run my app locally in RStudio (viewer pane or externally) it works perfectly as I want, but once deploying it I get errors and have to check the logs. This is my second app (my first one was much simpler) that I've tried making, so I have no idea what I've done wrong. I'll include the log output, and I'm using the PortfolioAnalytics package to optimise portfolios, then chart their weights, returns, and output text of annual return.

I would start from basics.
Make a more trivial app that just loads your libraries, and maybe shows a text output.
you could make it show you sessionInfo for example
then compare this to your working app which relies on the same libraries.
After that you could maybe try iteratively adding in parts of your app, though this may be somewhat arduous for you. On the other foot you might add print or cat or logger statements to print to console (i.e. shiny log) when you enter a function (reactive or otherwise) and leave it. My apps often has these as they can help alot if stacktraces are confusing/absent. (as can be the case in tidyverse ).
From the logs, I think output$WeightsPlot may be a culprit. But theres little to go on

good luck.

I am having a similar problem where my app works in Rstudio but fails to deploy. Thanks for any assistance:

Your issue seems to be a matter of the text encoding of your script, or some textual data you load.

I fixed the issue, it seemed that Shiny was publishing using a different version of some of the packages that messed with some elements of functionality in the "optimize.portfolio.rebalancing" causing it to default to outputting an error as a column vector (hence why none of the code afterwards, namely the plot and render text worked).
