Temboard not working with Pypi install | ERROR: tornado.general: Uncaught exception, closing connection.

[fxsoulis]

I have tornado error when i run temboard from a Pypi install whereas it works with a ubuntu22 package install.

$ sudo pip install temboard psycopg2-binary
$ temboard --version

temBoard 8.2.1 (/usr/local/bin/temboard)
System Ubuntu 22.04.1 LTS (Jammy Jellyfish)
Python 3.10.12 (/usr/bin/python3)
cryptography 3.4.8
Tornado 6.4
libpq 16.0
psycopg2 2.9.9 (dt dec pq3 ext lo64)
SQLAlchemy 1.4.50

$ sudo apt install temboard
$ temboard --version

temBoard 8.2.1 (/usr/lib/temboard/bin/temboard)
System Ubuntu 22.04.1 LTS (Jammy Jellyfish)
Python 3.10.12 (/usr/bin/python3)
cryptography 41.0.5
Tornado 6.3.3
libpq 14.10
psycopg2 2.9.2 (dt dec pq3 ext lo64)

I've retried a Pypi install with tornado v6.3.3 (same ubuntu package version) and it works.

Here is the error encountered when i load url from my web navigator with Pypi install as the documention :
