Using Virtual Agents in AXP

I have created a Dialogflow CX Agent (in Google) and added it as a Virtual Agent in AXP

From Orchestration I am getting detail: "Fail reason is unknown and unable to be handled by Connector" title: "Fail reason is unknown"
I can see from the logs on Google it is getting called

Do you have any ideas would this be happening or do you know if there is any logs I can look at in Orchestration?
