Hello,  
I have been using webservice authentication in ShinyProxy for a Shiny app. Recently I ran into some issues with the authentication in certain cases. The investigation points to escaping. I was wondering if it is possible for me to implement some kind of JSON escaping for the placeholders. Or else do you have any advice on escaping special characters when using webservice authentication with ShinyProxy?  
Very much appreciate your support.  
Thank you,  
Ferko

Hi

Unfortunately this is currently a limitation of the webservice auth. I created an internal ticket in order to fix this. It will be part of the next release.
