Failure when deploying client-side feature to monday-code (Might be a noob issue)

I’m trying to get a custom item-view built and deployed on monday-code, but seem to be failing.

Here’s what I did:

  • Ensured Monday CLI and mapps is installed and initialised with my API key
  • Created a new app on Monday
  • Added an item view feature using the react-quickstart
  • Ran the npx command to scaffold the app locally (And set up the URL generated by the mapps tunneling config)
  • Made a super-small change in the App.jsx, just to test whether may code is running
  • Previewed the app in the Monday interface (View Setup) to confirm all is working
  • Went to Feature Details > Feature deployment and selected “Client-side code via CLI”
  • Ran the provided command to push the code to monday-code

What happens:

  • I see that it did create the zip file (Which is pretty big: 85M)
  • But then it fails with this error:

Deploying client side files
› Deploying client zip (D:\Repos\Learning\monday\item_view\quickstart-react.zip) to cdn
× Deploying client side files [FAILED: Unexpected error occurred while communicating with the remote server]

I also tried
I also tried to deploy by manually uploading the zip file to monday-code using the “Client-side code via zip file (monday.com)” option, but this simply ran forever, never even timed out

So I guess I’m doing something wrong. Any suggestions?
