RESTful Raylight Error Incorrect session

Hello,

I'm starting my journey with RSDK and I have small issue here.

Based on SAP Web Intelligence RESTful web service SDK User Guide document I was able to retrieve my logon token, I can get info from infostore and document properties (with GET http://servername:6405/biprws/infostore, and so one). But then I tried to retrieve more details (GET http://servername:6405/biprws/raylight/v1/documents) I'm still getting:

401 Unauthorized

<error>

    <error_code>2</error_code>

    <message>Incorrect session found in HTTP header X-SAP-LogonToken (too many values)</message>

</error>

could you please help?

Many thanks
