Server Error When Following Tutorial: Database Connection Failed

I'm working through the tutorial at https://tutorial.microns-explorer.org/quickstart_notebooks/07-cave-download-skeleton.html and encountered a server error when running this example code.

from pcg_skel import get_meshwork_from_client

sk_mesh = get_meshwork_from_client(example_cell_id,
                                   client=client,
                                   synapses=True,
                                   restore_graph=True,
                                   restore_properties=True,
                                   skeleton_version=4,
)
sk_mesh

I'm using CAVEclient version 1412 of minne65_public

Output:
HTTPError: 500 Server Error: Cannot connect to database 'minnie65_public__mat1300'. Please check if the database exists and is accessible. Connection URI: postgres://postgres:welcometothematrix@127.0.0.1:3306/minnie65_public__mat1300. Error: (psycopg2.OperationalError) connection to server at "127.0.0.1", port 3306 failed: FATAL: database "minnie65_public__mat1300" does not exist

Is this a known issue with the database server, or am I missing a setup step? Any guidance would be appreciated.

Start with the quickstart notebook at tutorial.microns-explorer.org/quickstart_notebooks/07-cave-download-skeleton.html and reproduce the get_meshwork_from_client example using CAVEclient version 1412 of minne65_public. Investigate the reported PostgreSQL connection to minnie65_public__mat1300 and determine whether the tutorial is missing a setup step or references an unavailable database. Done means the example runs successfully or the tutorial clearly documents the required setup.
