login error after shiny timeout

[vdebuen]

Hello.

First of all I would like to thank you for this great clearance package.

In general it works quite well for both login and logout but sometimes I encounter problems when the shiny session gives timeout after a long time.

When you refresh the page with F5 it freezes and on the terminal where the application is running I get these messages.

Warning: Error in UseMethod: no applicable method for 'tbl_vars' applied to an object of class "list"
  69: tbl_vars_dispatch

I realise that it is not at all easy to reproduce this error, but perhaps with this information you can guess what might be happening and how to avoid it.

This is the information of the package I have installed, as shown in the R statement sessionInfo()$otherPkgs$shinyauthr

Thank you very much in advance

It would also be a good idea, for security reasons, for the system itself to logout when shiny goes into timeout and then require login again when the user returns.

did you find a solution? it seems this package is not maintained now.

@vdebuen @sanjmeh can you explain what you mean exactly by a shiny 'timeout' ? shinyauthr returns to a logged out state when a session is restarted (a page refresh for example). I'd need more information about what is happening during your app's 'timeout' to try to reproduce this.

I am sorry, it was while using shinymanager ( and I thought I was using shinyauthr). It seems shinymanager has this bug.

If shinyauthr is better shall I give it a try?
