Unable to Insert object to google cloud storage

[pebrianto]

Hi, I am able to get data from my bucket using postman. But not with uploading to my bucket. I have followed both simple and multipart upload but none works, even when I try with OAuth 2.0 Playground. The error message does not make sense as I followed the documentation and supplied the Authentication. 

Request Multipart:

Nevermind, I am now able to insert new object. After comparing with download request, I found that I used https://storage.googleapis.com as base url for upload, rather than https://googleapis.com. The url stated in official documentation uses storage in front of googleapis, so I followed it without thinking it is the issue.
