I am experiencing an issue in our ShinyProxy Environment - as the screen sometimes turns into grey when launching an application that I have just built.
Although I cannot share the app here - but it is actually super-simple. There is a navbarpage in the front and it loads a data (around 1000 rows and 50 columns) from our database and simply displays it with rhandsontable. Since it takes a lot of time to load, I use spinners - to show that the page is loading.
For reasons - I would not discuss here - it takes around 20s to load and display the table if everything works out all right.
Around 5 times out of 10 - the screen turns into grey before it loads the table in the main page. Every single time when the page fails to load - Chrome keeps telling me that the websocket connection failed.
In Rstudio - everything works just fine - and initialising the application on its own in seperate Docker image - it works all right. The error is not reproducible there. I tried everything I can - but I cannot figure out what is the root of the problem.
Neither the data nor the script does not have special characters - so it suprises me the Chrome says that it is related with UTF-8.
Since I have already launched quite a few applications with ShinyProxy - and I have never experienced anything like this - it remains an open question to me - what can cause this error.
When launcing the ShinyProxy in debug mode - it does not report any error message when the screen turns into grey…
If you have any idea, please let me know.
Thanks in advance,
