Getting undefine as prefix in Conference Status Hook

Hi Team
We are using the Dial to Conference Feature
When 2nd or 3rd Member Joins the conference we get undefined as the prefix in Hook, For 1st Member, the Status is coming correctly
"hook": "undefined/conference/status",
"data": {
"event": "join",
"duration": 0.945,
"time": "2024-06-24T07:30:28.046Z",
"members": 2,
"conference_sid": "conf:8422c26a-ac54-4b5e-8385-4891a9809511:89008b5b-797e-42e1-b4af-36ef5be11cfd"

Start by reviewing the attached New Panel logs and the code that emits the Conference Status Hook for the Dial to Conference feature. Compare the first member's hook with later joins and confirm that the hook prefix is defined for every member before adding a regression test or equivalent verification.
