Power BI REST API Table and Row query return with 404 error

Hello,

I get this issue when trying to access table and to add or delete rows using REST API. I followed the documentation example here

https://msdn.microsoft.com/en-us/library/mt147898.aspx

Error looks like a typical 404 error

The remote server returned an error: (404) Not Found.

I tried both my own workspace and group workspace (where i am the owner), using client id and client secret generated from 

https://dev.powerbi.com/apps

by ticking all access boxes to be true.

The weird thing is that group, dataset and report APIs still work but not for table and row. I like to use table and row api for managing the datasource. 

is there any thing in the middle not correct?
