Hooks testnet examples, docker image rippled node initialization

Attempting to play with rippled/hooks for first time. Using direction from following repo: https://github.com/XRPL-Labs/xrpld-hooks/tree/hooks-ssvm

After running container, seems like rippled node is running, but network state is disconnected when queried. Attempting to run/install any of the included example hooks results in : disconnecter, code: 1000, and RippledNotInitializedError.

Any chance someone could point me in the right direction here?
