Error when running on Shiny Server

[HashimNV]

I'm trying to run my application on Shiny Server. Everything works well except this package and I get the following error:

Uncaught TypeError: MutationObserver.observe: Argument 1 is not an object. https://shiny.abc.com/hnaveed/xyz_Dashboard/shinyglide-0.1/shinyglide.js:2 https://shiny.abc.com/hnaveed/xyz_Dashboard/shinyglide-0.1/shinyglide.js:2 https://shiny.abc.com/hnaveed/xyz_Dashboard/shinyglide-0.1/shinyglide.js:2

When I run the app with the shinyglide package on localhost, it works well. Only when it is run on Shiny Server does it throw these errors.

What do you think could be an issue?

Thanks in advance :)

Hi, do you know what versions of shiny and shinyglide are running on localhost and on your server ?

[HashimNV]

Shiny version: 1.8.0 shinyglide version: 0.1.4

[juba]

It is the same version both on localhost and on the server ?

[HashimNV]

I believe so as I'm not changing anything in the script. How do I check on the server?

[juba]

Hmm if you have access to the server you could just check what shiny version is installed there, otherwise maybe create a small shiny app that just displays it ?

There are more informations here I think : https://stackoverflow.com/questions/25992642/rstudio-shiny-how-can-i-display-the-version-of-the-shiny-server-in-the-shiny-pag

Another thing you can check, when your app is open in your browser, is to open the developer tools, go to console and type "window.Shiny".

Strange, I can't reproduce this problem with Shiny 1.8.0... Are you using the latest Github development version ?

The issue is resolved. There was an issue on the server side. It worked well when I fixed that. Thanks for the help and the package.
