在shinyapps 中立即断开与服务器的连接，本地工作，未报告错误

Question

After successfully deploying to shinyapps.io from Rstudio, the website initially loads, but then disconnects within 1-2 seconds.

• App: https://ts404.shinyapps.io/TopicNetwork
• Repo: https://github.com/TS404/TopicNetwork

The app runs fine locally, and no calculations should be performed before the "calculate network" action button is clicked. I've checked similar questions here (eg this ), however they don't seem applicable for such a small app. Is it anything to do with the github packages or D3? Any ideas?

Answer 1

Based on CJ Yetman's observation, I deactivated all unused packaged and reintroduced them one at a time to test. That narrowed the problem down to chorddiag , which it turns out needs to be attached by library() in both server.R and ui.R , even if none of its functions are be used in the app.
