Shiny App randomly crashes #244

Closed richpauloo closed 6 years ago

richpauloo commented 6 years ago

I get a similar error to this issue.

The app will work, but randomly it will crash and always give the same error:

Listening on http://127.0.0.1:4100
Warning: Error in sample.int: invalid first argument

After reading the linked issue, I updated my version of shiny, but the error persists. Here's a printout of my session info. If you have any idea what may be causing this, please let me know!

Without posting a reproducible example, there's not much I can do to help you... It seems like you're (either directly or indirectly) passing an argument to sample() that isn't valid. So, unlike the issue you linked to, your error is more likely coming from your own code, than from Shiny or shinydashboard. Do you have a small reproducible example you can share?

richpauloo commented 6 years ago

Hello, and sorry for wasting your time. This issue can be closed. I figured out the error, and it's wasn't Shiny, but as you suggested, an error in how I was sampling data. Thanks for pointing that out though! :)

Glad you figured it out! These types of questions can also be posted in our Shiny Google group: https://groups.google.com/forum/?nomobile=true#!forum/shiny-discuss

Since a lot more people subscribe to that, there's a greater chance you'll get an answer. It's also more appropriate when you need help with your app/are not sure what's wrong. Please include sample code/minimal reproducible example there as well.

This issue tracker is mostly used for reporting concrete bugs and to make new feature request.
