Axiom Not Returning Depending On Contents of Json

Question

I have an Python Flask api that is being called in a React app using Axiom. I'm using the following code in NameForm component to handle requests from my Flask api. import React from 'react'; import axios from 'axios';

class NameForm extends React.Component {
  constructor(props) {
    super(props);
    this.state = {value: ''};

    this.handleChange = this.handleChange.bind(this);
    this.handleSubmit = this.handleSubmit.bind(this);
  }

  handleChange(event) {
    this.setState({value: event.target.value});
  }

  handleSubmit(event) {

    axios.get('http://127.0.0.1:5000/api/'+this.state.value,)
  .then(function (response) {
    console.log(response.data); 
    console.log(response.status); 

  })
  .catch(function (error) {
    console.log(error);
  });

This code sometimes returns nothing and sometimes returns the contents from my Flask API depending on what content I generate on the backend.

Here is my backend code. For all requests, I see the request being made on the backend and see the data being printed. However, for some requests, I don't see anything returned to the front-end. The request that returns something when I have the first function is_original, but when I include the other functions below, I see nothing on the front-end. I'm very confused as to why some json is being returned while some other json is not being returned.

import json
from flask import Flask
from flask import jsonify
from dog_matcher import *
app = Flask(__name__)

@app.route("/api/<name>")
def hello(name):
    data = {}
    name = name.capitalize()
    data['is_original']= is_original(name, names_file[1:10])
    data['meta_names']= get_metaphone_closest(name, names_file)
    data['leven_names'] = get_levenshtein_closest(name, names_file)
    data['jaro_names']= get_jaro_closest(name, names_file)
    data['soundex']= get_soundex_closest(name, names_file)
    print(data)
    return jsonify(data)

if __name__ == "__main__":
    app.run(debug=True)

On the server, the following content is printed for the request "Jim" from the front-end. Nothing is returned on the frontend.
