Transform string to intergenerate JSON - Zabbix

Hello, I'm having the following problem, I'm trying to use the LLD method in zabbix to crawl a value.

I would like to generate the item as follows:

NAME ANY = VALUE (Numeric Type)

But I'm having a question if I'm generating my JSON correctly, because when I play it for Zabbix, it says that my JSON is generating the {# QTD} strong> String , and would like to generate it in type interger . So my doubt is if my JSON is performing the cast to interger correctly?

{
        "data":[

{"type": "integer","{#QTD}": 1 },
{"type": "integer","{#QTD}": 5 },
{"type": "integer","{#QTD}": 6 },
{"type": "integer","{#QTD}": 5 },
{"type": "integer","{#QTD}": 7 },
{"type": "integer","{#QTD}": 2 },
{"type": "integer","{#QTD}": 4 },
{"type": "integer","{#QTD}": 4 },
{"type": "integer","{#QTD}": 7 },
{"type": "integer","{#QTD}": 8 }
        ]
}

Performing test on the jsonlint site it informs that my JSON has no syntax errors.

Error that is occurring:

PS: GET_ALARM_LLD is a Macro that I use to run .sh that creates the indexing of my text output any to the JSON format.
