Uncaught ReferenceError: preShinyInit is not defined

[galen211]

I'm cross-posting this issue from the RStudio community site here because I'm not sure if it's a bug or not. I'm running a shiny-server docker container on kubernetes behind a load balancer. When I deploy my pod with shiny-server, I can see traffic routing into the pod and am getting partial page loads with a significant number of 400 errors on js and css assets.

In the console, I can see the aborted GET requests for the different assets along with a series of errors from shiny-server-client.min.js including Uncaught ReferenceError: preShinyInit is not defined

Looking for help to understand this exception.

The TypeErrors and ReferenceErrors are just symptoms of the failed GET requests. The GET requests are likely failing because of rstudio/httpuv#247. If you can get the load balancer to stop sending Content-Length: 0 on proxied GET requests, great; otherwise, you'll have to either install httpuv from GitHub master (i.e. remotes::install_github("rstudio/httpuv")) or wait for the new httpuv release to hit CRAN. We are in the submission process already, so hopefully any day now?
