Error return render_template

Hello,
I’m testing uploading a small app.py file with the following:

import sys,os
INTERP = os.path.join(os.environ['HOME'], 'www','.local', 'bin', 'python3.11')
sys.path.append("/home/qwertgolmar/www/.local/lib/python3.11/site-packages/")
from flask import Flask, render_template

from config import config

app = Flask(__name__)

@app.route('/test')
def test():
    return "<h1>Flask</h1>"

application = app

if __name__=='__main__':
    app.config.from_object(config['development'])
    application.run()

and now I modify the app.py by

import sys,os
INTERP = os.path.join(os.environ['HOME'], 'www','.local', 'bin', 'python3.11')
sys.path.append("/home/qwertgolmar/www/.local/lib/python3.11/site-packages/")
from flask import Flask, render_template

from config import config


app = Flask(__name__)

@app.route('/test')
def test():
    return render_template('auth/login2.html')

application = app

if __name__=='__main__':
    app.config.from_object(config['development'])
    application.run()

the html template is located inside the templates/auth folder

Because it gives an error and does not render the template
