CODE EXAMPLE FOR PYTHON

error handling in python using flask

from flask import Flask, abort
from auth import AuthError
# depending on the error either 400 or any
#just work with the following

@app.errorhandler(404)
def resource_not_found(error):
  return jsonify({
    "success":  True,
    "error": 404,
    "message": "Resource not found"
  }), 404
##This works for any type of status code error
#You'll follow the same steps just change the error value and message :)

### also for Auth error. 

@app.errorhandler(AuthError)
def AuthError(error):
  """Need to return JSON and we'll have to get a response""" 
  response = jsonify(error)
  response.status_code = error.status_code
  
  return response
