calling a logic-app from azure function

Trying to send http request from azure function to logic app. Function in Javascript runs without error but the logic app has never been triggered. Here is how i am fetching the endpoint.

 const fetch = require("node-fetch");

    fetch("https://prod-30.eastus2.logic.azure.com:443/workflows/123axc/triggers/manual/paths/invoke?api-version=2016-10-01&sp=%2Ftriggers%2Fmanual%2Frun&sv=1.0&sig=abc123-XKP-fPs",{method: "POST", body: {"html": html}, headers: {
        "Content-Type": "application/json",
      }})

Can someone explain what is wrong or missing here?
