Zabbix 5.4.10 CentOS appliance

JSON sample:
{
"Intf": "0/1",
"Detection": "Unknown",
"Class": "Unknown",
"Consumed": "0.00",
"Voltage": "0.00",
"Current": "0.00",
"WattHr": "0.00",
"Temperature": "N/A"
},
{
"Intf": "0/2",
"Detection": "Unknown",
"Class": "Unknown",
"Consumed": "0.00",
"Voltage": "46.81",
"Current": "0.00",
"WattHr": "0.00",
"Temperature": "N/A"
},

Data scraped from network switch, converted from CSV to JSON in item preprocessing.
discovery rule on json data has LLD macro {#IF} = "..Intf
item prototype uses JSONpath preprocessing:

$.[?(@.Intf == {$IF})].Voltage

If I have quotes around the macro I get "no data matches the specified path" which is likely because it is a valid jsonpath but no results.
If I DO NOT use quotes I get an invalid construct.

Copying and pasting the paths and sample data into online parsers works.

Of note, I am using the same macro in the name of the item prototype and it resolves to
Interface ["0/2"] voltage:

The macro is also in the key and resolves to
shitSw.["[\"0/2\"].Volt"]
