heroku is giving me Method not allowed

Question

Okay, so I've been on this problem for hours now with no idea how to solve this, since I'm just a newbie. I was following a UDEMY course titled WEBDEVBOOTCAMP by Colt Steele. On the deployment section, every time I deploy using Heroku, this gives me a "Method not allowed". I've been following Colt's ways from scratch and that's why I wonder how come it's like this.

These are the Heroku logs that I've been receiving:

Answer 1

From the Q&A on the webdevbootcamp video:

"Make sure you are trying to access the correct link that gets printed to the console. You shouldn't try to load the link which ends with .git since that is just the repository location.

Your link should look like https://your-app-name.herokuapp.com/"

Answer 2

I faced the same problem. Check your url, you might be opening the one which ends in .git. Instead go to your heroku dashboard and open the app from there using the correct url.

Answer 3

This Problem Bacicaly comes when you are using wrong link

Your link should be like https://test-name.herokuapp.com/

Answer 4

With reference to Matt's answer: -

Even if the deployment is successful, but you have not defined a html as to how the webpage should look like, then you get 'Method not allowed', meaning,
"https://your-app-name.herokuapp.com/" will have "Method not allowed".

But there is a way you can test if the deployment is done okay and you are getting Response 200.

Open jupyter notebook and run:
Reference: https://towardsdatascience.com/create-an-api-to-deploy-machine-learning-models-using-flask-and-heroku-67a011800c50

In short :

import requests
import json 
# local url
url = 'https://your-app.herokuapp.com/'

# sample data
data = {'Pclass': 3
      , 'Age': 2
      , 'SibSp': 1
      , 'Fare': 50}
data = json.dumps(data)

send_request = requests.post(url, data) #should get : Response 200

print(send_request.json())# should get predicted result

Answer 5

I faced the same issue while deploying a golang web app on heroku. The root cause of the issue was with how i frame the url. The url generated by heroku consisted of a trailing "/" and i was constructing the url as "heroku_url" + "/login" which resulted in heroku_url//login, try removing a / from heroku_url or from your route and give a try.

Answer 6

Before deploying your app make sure your project is on the main branch.

Refer: Git Branches.
