How do you access Axios response with Express?

I just started working with Express and am currently lost on how to make an Axios request using route parameters and change some locals based on what the request returns. This is what I have so far:

helpers.js

const axios = require('axios');
const {
  titleSuffix,
  organizationPath,
  varietyPath
} = require('./constants');

let organizationData = {};
let varietyData = {};

const Helpers = {

  fetchOrganization: (organizationID) => {
    axios.get(organizationPath + organizationID)
      .then( (response) => {
        //console.log(response);
        organizationData = response.data.data;
      })
      .catch( (error) => {
        //console.log(error);
      });
      return organizationData;
  },

  fetchVariety: (varietyID) => {
    axios.get(varietyPath + varietyID)
      .then( (response) => {
        //console.log(response);
        varietyData = response.data.data;
      })
      .catch( (error) => {
        //console.log(error);
      });
      return varietyData;
  },

  setOrgOpenGraphTags: (growerHash, res) => {
    Helpers.fetchOrganization(growerHash);
    res.locals.meta.og.title = organizationData.name + titleSuffix;
    console.log('Org = ' + organizationData.name);
  },

  setVarOpenGraphTags: (contextualId, res) => {
    Helpers.fetchVariety(contextualId);
    res.locals.meta.og.title = varietyData.name + titleSuffix;
    console.log('Var = ' + varietyData.name);
  }

};

module.exports = Helpers;

server.js

// Express
const express = require('express');
const app = express();

// Helpers
const {
  setOrgOpenGraphTags,
  setVarOpenGraphTags
} = require('./helpers');

// Organization
app.get(['/org/:growerHash/*', '/_org/:growerHash/*'], (req, res) => {
  setOrgOpenGraphTags(req.params.growerHash, res);
  res.render('org');
});

I'm fairly certain I'm missing something small but can't seem to get the following local changed based on the response from Axios:

res.locals.meta.og.title

Based on what I have so far how do I properly access the response from Axios in Express and change the locals? I really need an answer based around the code I've provided. Currently in my dev environment the request works but in production it returns "undefined". Thanks so much in advance.
