How do you debug cloudflare prod?

[tom-huntington]

I got an error in prod that didn't happen in dev.

I guessed eventually, but I couldn't find anyway to trouble shoot it.

I recall Otto using logs from the cloudflare dashboard, but couldn't find any to do it with a free account.

When I try wrangler tail I need a worker name

❯ wrangler tail
 ⛅️ wrangler 2.8.0 (update available 2.16.0)
------------------------------------------------------

✘ [ERROR] Required Worker name missing. Please specify the Worker name in wrangler.toml, or pass it as an argument with `wrangler tail <worker-name>`

Edit: The error was from Auth.js. When not using vercel (i.e. cloudflare pages) you need to do some things differently like set AUTH_TRUST_HOST: https://authjs.dev/reference/sveltekit
