Hi Everyone,
I wanted to share a quick update on this issue. We've been digging into these reports, and we believe we have found the issue. As of about an hour ago, a fix has been deployed which we believe has resolved the issue. If you're still seeing problems with your application, please restart or redeploy to ensure you have the latest changes. If the problems persist, please open a case with RStudio Support.
More details:
We recently pulled in an updated version of a shiny dependency that may have changed the way previously benign JavaScript errors were handled. While we're still trying to get to the bottom of the issue, it appears that some applications with unhandled JavaScript errors crashed when previously they were able to continue executing. We're not yet sure how these are related, but we've rolled back to the previous version of the dependency, which should solve the problem.
I apologize for the disruption this has caused. I will post more information here as necessary.
Regards,
-Andy
