Shiny App running on local computer but on Shinyapps.io it does not run any data manipulation. Shows no error.

sun · July 16, 2020, 1:16am

I am working on making an application to determine number of trees to be planted to offset carbon. It is a combination of flex board and story board where the application walk user through every step and give a cost benefit analysis.

My app is working on my local computer. Once I publish it on Shiny
https://mynewshinyapp.shinyapps.io/storyboard_goel/?_ga=2.44077156.1713991941.1594774021-1648084249.1582823449
the dashboard does not give any errors but it is not running any analysis.

I am attaching link to my GitHub ( the storyboard_goel.rmd under storyboard folder runs perfectly) https://github.com/sunaynagoel/urbanforest_CBA/tree/master/story%20board

I would appreciate any help.

Did you check the app run logs on shinyapps.io? This will show any console error messages. I usually write a lot of runtime messages to the console to assist in debugging.

Also there is a javascript console if you click Ctrl-Shift-J in the browser, which may give some information.

Problems when moving from RStudio to the web are often caused when the app can't find the data file.

I did check the run log. there is no error there as well. Here is a copy of app run log

I'm guessing the above log came from the shinyapps management console, which I'm not too fond off...
If so, it may be better to use the rsconnect::showlogs function with streaming parameter in your local R console , and then browse to the url in your browser, and then check in your local R console what happened.

Thanks for the input. Here is the log from local R console. I am not able to spot any abnormality.
