Failed to load resource: the server responded with a status of 500 ()

Hello, everyone. A couple of days ago, I encountered an issue while trying to display a report using shinyapps.io. To the best of my knowledge, no changes were made to the code. However, when I checked Chrome's developer console, I noticed the following error message: "Failed to load resource: the server responded with a status of 500 ()".

The logs only shows two lines with plausible relevance:

  • shinyapps[4630897]: Warning: Error in if: argument is of length zero
  • shinyapps[4630897]: 83: ui

I don't have any additional information to identify the specific "if" statement that is causing the error. Is there a possibility that this error was introduced in the most recent release? Perhaps someone might have a clue regarding "83: UI"?
Release (fb271f6e, 2023-05-09)

Thanks.
