"Impossible to update authenticatedCustomerId" error for authenticated messaging

[shenxin]

I am trying to do authenticated messaging.
I can successfully get token from Genesys API:
https://api.mypurecloud.de/api/v2/webdeployments/token/oauthcodegrantjwtexchange

But, when the chat initialized. I got this error in the websocket downstream data:
Impossible to update authenticatedCustomerId, then the web page looks like this:

My websocket upstream data is:

{
    "deploymentId": "97173f33-d29b-432a-b966-899fecb5d354",
    "token": "a774d5c0-0727-4c6a-9de5-254f6bc6f5d3",

            "idType": "cookie"
        },
        "customerSession": {
            "id": "7dd47e55-48ad-4de7-ab2f-c854e7daba7f",
            "type": "web"
        }
    },
    "action": "configureAuthenticatedSession",

    }
}

My downstream WS that is responding to above upstream data is:

{
    "type": "response",
    "class": "string",
    "code": 400,
    "body": "Impossible to update authenticatedCustomerId"
}

So what do you think is the issue? Any suggestion? Anything I missed?

Hi,

Thanks for reaching out.

It looks like you're not using the right JWT.
A first authenticated session was successfully configured with a given user (sub attribute in JWT) and linked to a given token (e.g. "a774d5c0-0727-4c6a-9de5-254f6bc6f5d3") that points to the Web Messaging session.
Once configured, authenticated user is tied to the session (hence the token) and cannot be changed.
Then subsequent session configuration requests reference a different user than the one assigned initially.
That is why you get this error message.

If you want to start a new session for a new different (authenticated) user, use a new token in the configureSession request.

If you're not falling in this use case, please let us know.

Hope this helps,

Best regards,
V.P.
