ACE 2.1 Kairos Workflow Error

Hi Team ,
I am exploring and replicating ACE 2.1 with Unreal engine .
I have downloaded the Kairos sample project and set it up with UE.
But if I am putting the microservice IP the Meta is not animating . it is in idle mode.
I got some UE blueprint error .

Some one can help me with this.
I have attached screenshots for reference
