Research direction

Start with app.R, the Data/ folder, and the DT::renderDataTable() call; inspect the failed Ajax request and 404 response in Chrome Developer Tools while running the Docker container. A useful resolution would reproduce the container behavior with the CSV and identify why the table request cannot find it, with the table loading successfully afterward.

Description

Hello,

I am running an R Shiny application on a docker container. My app directory consists of an app.R file and a Data/ folder. I have a feature where I use DT::renderDataTable() to render a .csv file stored in the Data/ folder. This feature works locally but produces this pop-up error when executed on the docker container:

DataTables warning: table id=DataTables_Table_0 - Ajax error. For more information about this error, please see http://datatables.net/tn/7

Following the link, I investigated the error using the Developer Tools pane in Google Chrome. As a result, I found that the server responded with a "404 - Not Found" error when trying to render the table. I made sure that the .csv file is present in the Data/ folder, so I'm not sure why I'm still getting this error. Any explanation on how to fix this issue would be greatly appreciated.

Thanks!
