Server Error When Following Tutorial: Database Connection Failed

[dhuruvapriyan]

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.

Thank you, this seems to be a bug with retrieving the synapses from the server. I will check with pcg_skel to see what has changed.

In the meantime you can set the argument synapses=False and the code will run, but you will not be able to complete the rest of the tutorial as written.

Found the underlying bug, track at this issue CAVEconnectome/MaterializationEngine#196
