Hi Matthew, we traced this using the character ID, so no additional session ID is needed.
The requests are reaching our backend, but speech generation is failing at ElevenLabs. The previous ElevenLabs credential is no longer accepted by their realtime service. After the integration was updated, the new credential was accepted, but it does not have access to the private voice currently assigned to this character, Old Dude Remix V2.
Please generate an ElevenLabs API key from the same ElevenLabs workspace that contains this voice, then update the ElevenLabs integration in Convai and start a new session. If the voice was deleted or belongs to another workspace, it will need to be restored, re-cloned, or replaced.
We’re sorry this affected your live project. Once the key and voice workspace are aligned, let us know and we’ll verify the character again.
