here is the node js test app

'use strict'

const { Client } = require('@elastic/elasticsearch')
const client = new Client({
  node: "http://localhost:9200",
  auth: {
    username:   use as appropriate
    password: 
  },
})

async function run () {

  // Let's search!
let result
  try{
    result = await client.search({
    index: 'logs-generic-default', 
    "query": {
      "bool": {
        "must": {
           "match_all": { }
        },
        "filter": {
          "geo_bounding_box": {
            "navigate_location": {  // or "fribble"    fribble gets variable not found, navigate returns no hits
              "top": 30.6627347,
              "bottom": 30.415,

          }
        }  
      }
  }


  })
 } catch(error){
    console.log("error="+JSON.stringify(error));
 }
 finally {
  console.log(result)
    const data = result.rows.map(row => {
    const obj = {}
    for (let i = 0; i < row.length; i++) {
       obj[result.columns[i].name] = row[i]
    }
    return obj
