I am working on a simple Shiny app that takes URLs from a published Google Sheet and obtains some information about them from the Zillow and Google Maps API. The app loads fine locally (using R Studio and clicking the "Run App" button). However, when I deploy the application, I get the following messages / error:
Preparing to deploy application...DONE
Uploading bundle for application: 274189...Error: C stack usage 7969528 is too close to the limit
Execution halted
A quick search of the error suggests that it indicates some sort of memory issue (i.e., here, possibly due to a typo or other error in the code causing some type of recursive loading of data). However, I've combed through and simplified the code, and can't seem to find the offender.
What is causing this error when deploying the app?
