Insights API call returns "Endpoint not found"

Hello,

I am trying to use the new Insights/summary API feature: https://api.typeform.com/insights/{formId}/summary 

However while all the others API calls are working fine, when i use my typeform token (Bearer xxxxxx) and my TypeFormId when i try to get the insights on my surveys, i get the following response: 

{"code":"NOT_FOUND","description":"Endpoint not found"}

Am i missing something ? Or is the feature not available yet ?

EDIT: Never mind, it was a silly mistake on my part, I missed a blank character at the end of my query, I saw it after checking the reques in notepad++

So this is solved !

Thank you
