cache-handler: Missing response on cached paths

Cache misses on first request and hits on next, that’s fine. But I no longer receive a response from the endpoint.

This is my Caddyfile.

{
	order cache before rewrite
	cache
}

:{$APP_PORT} {
	handle_path /api/* {
		reverse_proxy http://localhost:{$SERVER_PORT} {
			transport http {
				versions h2c
			}
		}
	}

	handle_path /api/v1/translate {
		cache {
			allowed_http_verbs POST
			ttl 24h
		}
	}
}

Logs from cURL.
