Google Cloud Storage - upload error: rename operation gcs-resumable-upload.json not allowed

Question

I'm just trying to follow this tutorial on how to upload files to gcs using Node and Express. But the following error causes my application to crash. As a rule, I can upload one file without problems in the first run. But I will get this error after running multiple requests even in another file. When I try to upload, say, 5 files at a time, this error causes my application to crash even on the first run. I see that the process is trying to rename the file in the .config folder. Is this normal behavior? If so, is there a job?
