Error 400 testing Postman API and how to get the same result as the tutorial

Hi Cognite community,

Since the available answers are not really, really clear on this topic, I am just posting my experience.

When using postman and following the tutorial, once you click on SEND, you get the 400 error code.

  

Error 400 while all parameters are checked

Just unselect all the parameters and retry and it should okay.
 

Parameters unchecked and result in the Body

For all the newbies like me, I hope this helps.
