ERROR! PLUGIN FAILED ON INITIALIZATION THEREFORE IGNORING!

Hello!
When I run the ambf_simulator command, the components don't seem to initialize correctly. Also, the ambf_client can't seem to connect to the simulator, so I can't obtain the simulation instance. Here is my code, taking the tasks in https://github.com/WPI-AIM/ambf/wiki/Controlling-dVRK-Manipulators as an example.
(accel_challenge) robot@robot:~/ambf/build$ ambf_simulator -l 4,5,6

This is the code I used in another terminal to test the ambf_client.
(accel_challenge) robot@robot:~/ambf/build$ python
Python 3.7.12 | packaged by conda-forge | (default, Oct 26 2021, 06:08:21)
[GCC 9.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

from ambf_client import Client
client = Client()
client.connect()
Found Common Object Namespace as:
print(client.get_ogj_names())
Traceback (most recent call last):
File "", line 1, in
AttributeError: 'Client' object has no attribute 'get_ogj_names'
print(client.get_obj_names())

I also ran the roscore command in another terminal.
Thank you!
