[patricegautier]

which platform are you running the zabbix server on?

What's the result of running

The 'expect' package needs to installed..

I noticed the same issue on Ubuntu 20.04. I was seeing the error about /usr/bin/expect was missing. The commands to install expect:

sudo apt-get update sudo apt-get install expect

The above commands installed the package and now the folder /usr/bin/expect exists. Now to continue the troubleshooting.

so looks like this particular issue is closed..
