nullpointer exception on startup

We try to install tibco-ebx 5.9.13 on RHEL 7, and an empty db was created (postgresql 11) and created a ebx db user with oowner access. it deployed service on the 2 nodes successfully, however when the ebx starts, it encountered a nullpointer exception after showing the repository is ready.
