How do You simulate Requests using Already placed Json Data with python/flask

Question

New to this, How do you simulate a HTTP Request with data which is already json and send it thru requests in python. I am trying to do it and its telling me, JSON Not serializable.

these are the lines of code which I am using

@app.route('/api/create-virtual-account',methods=['POST'])
@jwt_required()
def create_virtual_account():
    current_user = get_jwt_identity()
    _json = request.json
    _account_name = _json['account_name']
    _email = current_user
    _bvn = _json['bvn']
    _tx_ref = 'VAL12'
    _phonenumber = _json['phonenumber']
    _firstname = _json['firstname']
    _lastname = _json['lastname']
    _narration = _json['narration']

    url = 'URL HERE'

    data = {'account_name':_account_name,'email':_email,'bvn':_bvn,'phonenumber':_phonenumber,'firstname':_firstname,'lastname':_lastname,'narration':_narration}
    res = requests.post(url, data=json.dumps(data),headers={'Content-Type':'application/json','Authorization':'Bearer FLWSECK_TEST-72fe360edef17334f4817a17407011bb-X'})
    
    return jsonify({'result':res.content}),200

I know there is something i am missing, only i am not sure what it is. I am fairly new to this, so I need guidance

This is the Error i am getting

Instead of using res.content use res.json(). .json() method will parse the Json response to Python objects so you can use jsonify() method without error:

...

return jsonify({'result':res.json()}),200
