`npx wrangler rollback`

npx wrangler rollback [<version-id>] [--message <text>]

Risk: Careful

What it does

Sends all traffic back to an older version. Code only: data and bindings stay as they are.

When a smoke test or the error graph says the new version is bad.

$ npx wrangler rollback --message "Smoke test failed"

Go back to the version before the latest, with a note why.

$ npx wrangler rollback --env staging

Roll back the staging copy only.
