TypeError: undefined is not an object in shiny

TypeError: undefined is not an object (evaluating 'results.filter') htmlwidgets.js:475 find htmlwidgets.js:475 a shiny.min.js:3 f shiny.min.js:3 initShiny

Hello.

I want to apply the papaya widget to the shiny app, but I get the above error. In my opinion, it seems that you can not find the filter method rather than recognizing the results variable. Is there a solution?

Code to read a CT image using a papaya package in a Shiny app. If you compile and run the app after writing this code, the above error will occur.

What versions of the packages are you using? See devtools::session_info(). Also please attach the CT image.

CT image is Kaggle sample DICOM https://www.kaggle.com/gpreda/visualize-ct-dicom-data/data

Please upload a zip file with the data and create a MCVE: https://stackoverflow.com/help/mcve. Please upload the full R code. For example, imageTensor is read in somewhere else but does not appear in the app.R at all .

Thank you for your help. This is a problem only on the Ubuntu Linux operating system I use.

I noticed that the Chrome browser on Ubuntu Linux was not recognized properly and prompted me to download the browser again.
