LLD issue - cannot retrieve value of tag "key"

[cedric.marcoux]

Hello, i'm using a powershell script for LLD on Windows. This script return interesting NIC for retrieving perf_counter of all NICS.
The powershell code is working well from command line and return a valid JSON response, however Zabbix cannot interpret it and give an error cannot retrieve value of tag "key"
Here is the script you can test and see that the json is valid. The script has been coded to avoid escaping special char in code.

I forgot to put the JSON response with the power shell script:

{
 "data":[

{ "{#NICNUMLET}" : "vmxnet3 Ethernet Adapter" }

 ]
}

The code is valid based on https://jsonlint.com/
