Flask: Why does my server stall when I 'import requests'?

Question

SCENARIO

I am using a python flask server to serve up data from my remote database. I am tempting to use the requests framework to connect to my database with a held connection.

TECHNOLOGY USED

• Python 3.10
• Flask 2.0.3
• Poetry 1.0 (for dependencies)
• Requests 2.28.1 (added with Poetry)
• IBM Code Engine (cloud platform/environment)

ISSUE

My project works just fine up until I add the line import request at the top of my server.py. When I add this line no responses are given by my server and it times out.

CODE

The below outputs { "hello": "there" }, because import requests was not added.

import os
import sys
import json
from collections import Counter
from flask import Flask, render_template, request, session, url_for, jsonify

app = Flask(__name__)

@app.route('/', methods=['POST', 'GET'])
def main():
    return { 'hello': "there" }

if __name__ == 'main':
    app.run()

The below stalls and servers no response, because import requests was added.

import os
import sys
import json
import requests # adding this
from collections import Counter
from flask import Flask, render_template, request, session, url_for, jsonify

app = Flask(__name__)

@app.route('/', methods=['POST', 'GET'])
def main():
    return { 'hello': "there" }

if __name__ == 'main':
    app.run()

QUESTION

Why can't I import requests, and if I'm missing something could you please leave a code answer as to what I need to do to get this working?

(I've noticed some other frameworks can't be imported either)
