When deleting a migration using npx wrangler deploy --delete-class <ClassName>, you may encounter this error: "Cannot apply --delete-class migration to class <ClassName> without also removing the binding that references it". You should remove the corresponding binding under [durable_objects] in wrangler.toml before attempting to apply --delete-class again.
