java.lang.reflect.InvocationTargetException

I’m trying to connect to a topic created in GCP pub/sub from Foundry. I configured the necessary egress settings and white listed default Pub/Sub API hostname (pubsub.googleapis.com:443).

With this egress, I was able to pull the record onto code workspace. But for the same connection, if I try to create a streaming sync and try to build it, I’m getting this error (java.lang.reflect.InvocationTargetException). I’ve even whitelisted Foundry’s external IP range in GCP.
