[BUG] get_neurons_in_volume() does not work #2317

Description

@Leon-Parepko
  • PYMAID version: 2.4.2
  • CATMAID instance: None
  • Browser: No
  • Operating system: Win 10

Short description

Catmaid (pymaid) function get_neurons_in_volume() fails on the server side for L1EM connectome. I have used the pymaid via jupyter and tried to load the volume neurons data from L1EM, but it seems that it fails with the 500 error code on the server side. So looks like it is not pymaid issue, but some sever core code.

To reproduce

import pymaid

# Replace with your credentials
url = 'https://l1em.catmaid.virtualflybrain.org'
token = None
name = None
password = None

# Initialize CATMAID instance
rm = pymaid.CatmaidInstance(url, token, name, password)

pymaid.get_neurons_in_volume('SEZ_right')

More information
