I've resurrected an old shiny application developed by someone else and have been able to download the right packages versions using an older version of R (3.3.2). However, when I try and deploy the app, I get the following error:

Error: Unhandled Exception: Child Task 1268176331 failed: Error building image: R version 3.3.2 currently unavailable
In addition: Warning messages:
1: invalid uid value replaced by that for user 'nobody'
2: invalid gid value replaced by that for user 'nobody'

Is there any way I can get around this as I cannot use another version of R?

I've also tried deploying to RStudio Connect but that required me to update the shiny package which I also cannot do.
