Session ID returned unexpected results (looks ALB or load balancer, cookie format)

I refer to

https://docs.d-id.com/reference/createagentstream

https://api.d-id.com/agents/{agentId}/streams

but returned unexpected session_id, its looks like ALB cookie.

"session_id": "AWSALB=pXEctUwPeeHbAfnKx6q1YRILaiYLgAUkwEU0sYld0o4DK6KVchrWLYb6UKltvH3Lw7O33C++HjUPmKaNmdefdz52WSgOiqCcsiR3k4cB0UCtiVE/QuLxY07ban7h; Expires=Thu, 17 Apr 2025 11:30:29 GMT; Path=/; AWSALBCORS=pXEctUwPeeHbAfnKx6q1YRILaiYLgAUkwEU0sYld0o4DK6KVchrWLYb6UKltvH3Lw7O33C++HjUPmKaNmdefdz52WSgOiqCcsiR3k4cB0UCtiVE/QuLxY07ban7h; Expires=Thu, 17 Apr 2025 11:30:29 GMT; Path=/; SameSite=None; Secure"

Please elaborate, thanks.
