Failed to send pm2 data to Zabbix server getting "code":1

[nshah14285]

Hello,

Not able to send pm2 processes to the Zabbix server using pm2-zabbix. Getting below error.
It was working fine with Ubuntu 16.04. After upgrading to Ubuntu 18.04 it stopped working.
How to fix it? Any idea?

Zabbix agent: 4.0.22
Ubuntu: 18.04

I am facing the same issue.
Were you able to find what was causing this problem?
