Google Cloud Storage node

Hm... I have a question regarding the Google Cloud Storage nodes: I am creating a text file in a subfolder (mainly to create the folder for later), but I also want to make this file public accessible. The "Upload External..." nodes, who work perfectly, reference the bucket with "process.env.BUCKET", but it looks like I can't use this. Okay, using the bucket ID from the project preferences, I get the error "no such object", however, the file creation node finished successful?
