Parse Server instance stops working if I add GCSAdapter - node.js

Question

Im doing migration to parse server. And until now everything worked well. But now I want to add google cloud storage file adapter and if I add this line to my code it stops working. Can you somebody tell me why.
var GCSAdapter = require('parse-server-gcs-adapter');
