I am creating a javascript function to use in glideapps, following this process. The function takes in a google maps api url as a string input, and returns the json file as a string output. Using the example from google, I created this test which works fine.

function test(request_url){
  var axios = require('axios');
  var config = {
    method: 'get',
    url: request_url,
    headers: { }
  };

  var final = axios(config)
  .then(function (response) {
    console.log(JSON.stringify(response.data));
  })
  .catch(function (error) {
    console.log(error);
  })
  return final}

When I use the same function in the code for the glideapp function, I get two errors. First, I got the error: Error: Module name "axios" has not been loaded yet for context: _. Use require([]) and addressed it by using var axios = require(['foo'], function (foo) instead.

window.function=function(request_url){ 
  var axios = require(['axios'], function (axios) {
    //axios is now loaded.
  });
  var config = {
    method: 'get',
    url: request_url,
    headers: { }
  };

  var final = axios(config)
  .then(function (response) {
    console.log(JSON.stringify(response.data));
  })
  .catch(function (error) {
    console.log(error);
  })
  return final}

Now I get the error TypeError: axios(...).then is not a function. How do I fix this? Thank you
