Value should be a JSON object

[rluisr]

I tried to use LLD with my original script.
But zabbix say error Value should be a JSON object.

Execute my script on bash.

root@proxmox:/etc/zabbix# php zfspool_discover.php

{
	"data":[
	{
		"{#ZPOOLNAME}":"anypool"
	},
	{
		"{#ZPOOLNAME}":"prdpool"
	},
	{
		"{#ZPOOLNAME}":"rpool"
	}
	]
}

I made LLD script in the past. (https://github.com/rluisr/Zabbix-LXC)
But it doesn't work this time.

Zabbix server and agent is wrong version but other LLD script is work.

How I solve this problem?

Zabbix server
3.2.3

Zabbix agent
3.0.7
