First Time trying to Deploy to Heroku

Question

This is my first time trying to deploy to Heroku and I keep getting application error. I have the CLI and it is giving me logs but I'm having trouble trying to comprehend it. Any help is appreciated. Here are the logs...

$ heroku logs --tail -a weather-project-test

And lastly my code for app.py

from flask import Flask, render_template
from logging import debug
from flask_pymongo import PyMongo
from werkzeug.utils import append_slash_redirect, redirect
from script import api_call
import easygui

app = Flask(__name__)


@app.route('/')
def home():
    return render_template('index.html')

@app.route("/script")
def script():
    api_call()
    easygui.msgbox("Database Updated Successfully!", "Success")
    return redirect("/")

@app.route("/heatmap")
def heatmap():
    return render_template('heatmap.html')
       

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

Answer 1

This was an issue with easygui and trying to import tkinter. After that render template wasn't working correctly. I was ale to restructure the files and all is well. Thanks!
