Flask API TypeError: Object of type 'Response' is not JSON serializable

Question

i have a problem with Python Flask Restful API and data goes to Elasticsearch, when i post a new data with Postman, problem is:

TypeError: Object of type \'Response\' is

Answer 1

def post(self):
    some_json=request.get_json()
    return jsonify({'you sent ':some_json})

enough to solve this issue

Answer 2

Inspired from this bug, here is a shorter way of doing it:

from flask import jsonify, make_response

def myMethod():
    ....
    return make_response(jsonify(data), 200)

Answer 3

This can be simply done by:

from flask import jsonify
def myMethod():
    ....
    response = jsonify(data)
    response.status_code = 200 # or 400 or whatever
    return response

Answer 4

I had a similar problem, the problem is that i was using jsonify twice (jsonify(jsonify({abc:123})))
