我在运行已在本地运行良好的已部署Shiny.io应用程序时遇到问题。这是部署：
> rsconnect::deployApp(appDir = getwd(), server='shinyapps.io', appName='waters', account='yettas', launch.browser=TRUE)
Preparing to deploy application...DONE
Uploading bundle for application: 779726...DONE
Deploying bundle: 1929307 for application: 779726 ...

rollforward: Activating new instances
success: Stopping old instances
Application successfully deployed to https://yettas.shinyapps.io/waters/
启动应用程序时，显示此错误：
An error has occurred
The application failed to start (exited with code 1).
Error in value[[3L]](cond) : argument is of length zero
Calls: local ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous>
Execution halted
我不知道该如何调试或获取回溯。我的代码没有任何try-catch块，因此错误必须在包内部。这似乎相关，是否暗示该应用太大？ What is Error in value[[3L]](cond) in R?
建议会有所帮助。
