My LLD Macros ({#PORT}=$.[*]["6"]

ITEM Prototype has a Type Trapper

Name: portname"{#PORT}"
Type: Zabbix trapper
Key: port[{#PORT}]
Type of information:Text

If i execute the Discovery Role i get
"Cannot create item: item with the same key "port[{#PORT}]" already exists.
Cannot create item: item with the same key "port[{#PORT}]" already exists."

The JSONPath for your LLD macro should be from individual item in the data array. So, for {#PORT} instead of $.[*]["6"], it should just be $["6"].
Make use of the preprocessing testing¹ to test your expression.
