Looks like you're trying to load some js / assets from a different origin than your webserver. Are you using the file:/// protocol ? If yes, you shouldn't (generally speaking, it's always a bit difficult to work with this protocol : a lot of differences between browsers, some security policy that will make your website crash etc...)

Hello,
I cannot display correctly "lyon" example data with lopocs due to this error:
psycopg2.pool.PoolError: connection pool exhausted
As i'm not a programmer and I had to do some changes to make lopocs works on Debian (see at the bottom), I wonder if it can be due to my modifications or if there are some settings to change in the pool side
Following, part of the log:

and in the attached image what I see
My configuration:
VMWare Player Virtal machine, 40 giga hd, 4096MB of memory for the VM (32 Giga for the host)
Debian 10 stable
PostgreSQL 11 (repository)
PDAL (from GIT to have lazperf and laszip)
I did some changes in the following files:
setup.py
-- 'pyproj==1.9.5.1',
'pyproj==1.9.6',
-- downgrade
'werkzeug==0.16.1'
lopocs/cli.py
-- offset_x = summary['bounds']['X']['min'] + (summary['bounds']['X']['max'] - summary['bounds']['X']['min']) / 2
-- offset_y = summary['bounds']['Y']['min'] + (summary['bounds']['Y']['max'] - summary['bounds']['Y']['min']) / 2
-- offset_z = summary['bounds']['Z']['min'] + (summary['bounds']['Z']['max'] - summary['bounds']['Z']['min']) / 2
offset_x = summary['bounds']['minx'] + (summary['bounds']['maxx'] - summary['bounds']['minx']) / 2
offset_y = summary['bounds']['miny'] + (summary['bounds']['maxy'] - summary['bounds']['miny']) / 2
offset_z = summary['bounds']['minz'] + (summary['bounds']['maxz'] - summary['bounds']['minz']) / 2
-- xmin, ymin, zmin = transform(pini, pout, summary['bounds']['X']['min'], summary['bounds']['Y']['min'], summary['bounds']['Z']['min'])
-- xmax, ymax, zmax = transform(pini, pout, summary['bounds']['X']['max'], summary['bounds']['Y']['max'], summary['bounds']['Z']['max'])
xmin, ymin, zmin = transform(pini, pout, summary['bounds']['minx'], summary['bounds']['miny'], summary['bounds']['minz'])
xmax, ymax, zmax = transform(pini, pout, summary['bounds']['maxx'], summary['bounds']['maxy'], summary['bounds']['maxz'])
lopocs/database.py
server_version = full_server_version.split()[0] # Keep only "X.X.X"
-- server_version = server_version_full.split()[0] # Keep only "X.X.X"
(venv) root@sdi:/opt/lopocs# lopocs demo --sample lyon --work-dir demos --server-url http://192.168.0.120:5000 --cesium
ln -s /opt/lopocs/demos/ /var/www/html/lopocs
(venv) root@sdi:/opt/lopocs# lopocs serve --host 192.168.0.120
from lopocs.

Partially solved modifying row 193 in lopocs/database.py, and putting a different maxconn number in ThreadedConnectionPool
# cls.pool = ThreadedConnectionPool(1, cpu_count(), query_con)
cls.pool = ThreadedConnectionPool(1, 50, query_con)
But I really don't know what kind of consequences it could arise
from lopocs.
