Unable to send data into jsonParam

Hello Dev

This is my trigger

use system CALL apoc.trigger.install(
    'neo4j',
    'updateThreshold',
    'UNWIND apoc.trigger.propertiesByKey($assignedNodeProperties,"threshold") as properties
   with properties.node AS node, properties.key AS key, properties.old AS oldValue, properties.new AS newValue
   CALL apoc.load.jsonParams("https://function-sli-digital-twin.azurewebsites.net/api/create-threshold-request",
    {method:"POST",\`Content-Type\`:"application/json; charset=utf-8"},
   apoc.convert.toJson({oldValue:oldValue,newValue:newValue,key:key})) yield value return value
   ',{phase:'before'});`

when i will update my threshold value then this trigger should call and send respective data with this API

Trigger is working but request body is getting null

This is my javscript code

app.http('create-threshold-request', {
    methods: ['POST'],
    authLevel: 'function',
    handler: async (req, context) => {
            context.log("Body Data " + req.body);
        }
}

When iam trying to call this API on postman its working fine no issue at all

is there any another approch to send data
please help.

The documentation describes the load json api as an api that reads from the url. Don’t you want to send to your url?
