Problems when create map Zabbix 4.0.5

[buddhainkovy]

Hi, Prototype-X!
I have fresh install Ubuntu 18.04 + Python3.6 + Zabbix 4.0.5 and сonsistently followed your instruction.
I run command:
python3.6 weathermap.py -d -s core -z http://10.1.39.20/zabbix -l admin -p admin
Where -l admin -p admin - my current account in zabbix
and core - existing in zabbix map with a couple hosts and links.

and catch trace:
