I am trying to monitor the Dell EMC PowerVault ME4024, but due to limitations I am forced to use API instead of SNMP. As a result, I am using a Python3 script to grab the JSON.

Steps to reproduce:

1. Created an Item "Discovery Controllers", to generate the JSON (file: controllers.json) > working
2. Created Discovery Rule with the following settings:
   • Type: Dependent item
   • Master item: Discovery Controllers
   • LLD macro: {#ID} - JSONPath: $..['durable-id']
3. Created Item Prototype with the following settings:
   • Name: Controller: {#ID}
   • Type: Dependent item
   • Key: cntrl.{#ID}
   • Master item: Discovery Controllers
   • Preprocessing steps:
     • JSONPath: $[?(@.'durable-id' == '\{#ID}')]
     • Trim: []"

Result:

Expected:
What I try to achieve is to generate individual items.
