FMODStudioNiagara cook failure

Unreal Engine

We are on FMOD version 2.02.20 running on UE 5.1

We have FMOD integrated correctly and it builds fine. We tried using FMODStudioNiagara to add a PlayFMODEvent attribute to a Niagara system and it results in a cook error:

Seems like it’s not linking up correctly to some dll or script? What are we missing?

Are you able to share how you are using FMOD in the Niagara emitter?

Is there anything interesting in the logs?
Does this happen every time? Even after a reload and/or reboot?
