shinyapps.io deployment: Error building image

shiny shinyapps.io
1

I'm trying out the free version of shinyapps.io, and I've run across a problem deploying my app. It looks like it's having trouble deploying a package while the image is being created. I've been getting the same error for a few days, so I thought I'd report the issue in case it's a system problem.

Here's the log:

Found an answer to this in Scott's post here: https://forum.posit.co/t/shiny-app-fails-for-deploy-after-updating-all-packages-the-url-is-scottkbrown-shinyapps-io-gcstats/28842

The application has been deployed, but now the application has failed to start with the following message:
