Hey @fair bolt!

It looks like you pasted Python code without syntax highlighting.

Please use syntax highlighting to improve the legibility of your code and make it easier for us to help you.

To do this, use the following method:
```py
print('Hello, world!')
```

This will result in the following:

print('Hello, world!')```
You can **edit your original message** to correct your code block.

Python help channel opened

Remember to:

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

Closes after a period of inactivity, or when you send !close.

You don't need to do those add response headers

But move them into your CORS

Here's mine:
CORS(app, resources={r"/*": {"origins": ["http://localhost:9000", "*"]}})

ive added it

import json
from flask import Flask, jsonify, request
from flask_cors import CORS

app = Flask(__name__)

# CORS configuration
@app.after_request
def after_request(response):
    response.headers.add('Access-Control-Allow-Origin', '*')
    response.headers.add('Access-Control-Allow-Headers', 'Content-Type,Authorization')
    response.headers.add('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE,OPTIONS')
    return response


def application(environ, start_response):
  if environ['REQUEST_METHOD'] == 'OPTIONS':
    start_response(
      '200 OK',
      [
        ('Content-Type', 'application/json'),
        ('Access-Control-Allow-Origin', '*'),

it works when i visit the browser but when i try to call fetch from nextjs it does 403

Reason: Multiple CORS header 'Access-Control-Allow-Origin' not allowed
