I am attempting to run a flask backend server with flask. Whenever I run: python3 server.py The server hosts and whenever I go to it, it gives an error 404 not found. Here is the code: from flask import Flask, request, jsonify from flask_cors import CORS import subprocess app = Flask(__name__) CORS(app) # Enable CORS for all routes @app.before_request def before_request(): print(f"Request path: {request.path}") @app.route('/execute-file/', methods=['POST']) def execute_file(): try: # Get the file name from the request body fileName = request.form.get('fileName') if not fileName: return jsonify({'success': False, 'error': 'File name not provided'}) # Execute the file result = subprocess.run(['python', f'lib/execute/{fileName}'], capture_output=True, text=True) if result.returncode == 0: return jsonify({'success': True, 'output': result.stdout}) else: return jsonify({'success': False, 'error': result.stderr}) except Exception as e: return jsonify({'success': False, 'error': str(e)}) if __name__ == '__main__': app.run(host='0.0.0.0', port=8000) The error itself says: Not Found The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again. console displays the following: * Serving Flask app 'server' * Debug mode: off WARNING: This is a development server.
