Blooper: The Disappearing Cloudflare Variables

The Blunder

I kept adding MATRIX_URL and MATRIX_SERVER_NAME to the Cloudflare dashboard as plain text environment variables. Every time I ran wrangler deploy, they vanished into the void.

The "Duh" Moment

Wrangler is a neat freak. If a plain text variable isn't explicitly written in the wrangler.toml file, Wrangler deletes it from Cloudflare during deployment to keep the deployed state perfectly synced with the repository configuration. (Secrets, thankfully, are spared from this purge).

The Fix

Just hardcode the non-secret URLs in wrangler.toml under [vars]. Problem solved! 🤦‍♂️
