I'm playing on Xbox One X, with the patch that was released today (version 1.1.1 - 11/19/2019) - same issue here. Pavarti is alive, and offers this quest, but halfway through speaking with her, the quest fails because she is dead. Would really like for this bug to get fixed so I can complete this question - and also so I can re-complete the game and not have it tell me she's dead at the end.
No spoilers, but this bug does affect the ending, unfortunately.
