I have notice a little problem on LLD feature. if i create a wrong JSON output for LLD feature Zabbix don't check the correct syntax and it work for only the first element of the JSON list, i think is good to put in evidence this kind of problem from Web GUI frontend or in the log file.

Example of wrong JSON output (missing "," between element):

---

{
"data":[

{
"

{#DBNAME}":"information_schema" }
{
"{#DBNAME}

":"mysql" }
{
"

{#DBNAME}":"performance_schema" }
{
"{#DBNAME}

":"test" }
{
"

{#DBNAME}

":"zabbix" }

]
}
