Hello everyone, 

Please find below the issue encountered.

I am using the system run key to get a docker image version.

The command i have works fine but for a specific reason, i am created a calculated item, unfortunately it does not work, i believe because it needs to be in text type and not in numeric mode.

Steps to reproduce:

1. Create a zabbix-agent item using the system run key below :
   (system.run[sudo docker ps | grep "name of the container" | cut -d':' -f 2 | cut -c1-9]), output works great
2. Create a calculated item and get the last information above with the following formula : 
   last(system.run[sudo docker ps | grep "navineo-pc-integ" | cut -d':' -f 2 | cut -c1-9])

Result:
See screenshot for more information
