Where is this shiny app being deployed to?
Other than the code 137, I don't see an issue with your packages, just informational messages.
I've seen this error message occur where the application attempts to use more memory than is available to it on shinyapps.io
If you're working with shinyapps.io, that solution points to a section in the user-guide on memory.
You can see if you ran out of memory by looking at the shiny logs, Shiny Server Error Logs. I'd expect to see a message like "Out of memory" there.
If that is the cause of this issue, you can increase the memory available or possibly retool the app to use less memory.
