Unable To Fetch The affinityToken From SessionId API In Live Agent REST API

• According to the salesforce documentation to get the affinityToken first in headers you  have to set the X-LIVEAGENT-AFFINITY as null.

• If your not setting or if your not passing this header without null value in your request will not receive any affinityToken.
