I started up a new project on AWS C9 platform and i have a problem with rendering a web page with the framework Flask
The framework runs properly it can return messages (by default) but when i try to return a template(Html page) i receive the error: "TemplateNotFound" I will leave the code below and the error messages
import os
from flask import Flask, render_template, request
app = Flask(__name__)
@app.route("/")
@app.route("/home")
def home():
return render_template('templates/home.html')
@app.route("/about")
def about():
return "<h1>Flask is working</h1>"
if __name__=="__main__":
app.run(host='0.0.0.0', port=8080)
app.debug = True
Stack trace:-

By default flask looks for html templates in templates folder. You dont need to explicitly append /templates in your return statement.
Use this
return render_template('home.html')
