Error in saving data to mongodb database using flask - mongodb

Question

I am using a mongodb database with my app in Flask, and I am connecting it to the app with pymongo.
I am having an issue while trying to save documents in my mongodb database, see the error below :
127.0.0.1 - - [01/Oct/2019 15:56:47] "POST /movie HTTP/1.1" 500 -
Traceback (most recent call last):
File "/home/lancelot/.local/lib/python3.6/site-packages/pymongo/mongo_client.py", line 1385, in _retry_with_session
return func(session, sock_info, retryable)

raise OperationFailure(msg % errmsg, code, response)
pymongo.errors.OperationFailure: Transaction numbers are only allowed on storage engines that support document-level locking
This is my views function which is catching the post request :
#app.route('/movie', methods = ['GET','POST'])
def add_movie():
movie = mongo.db.movies
try :
name = request.json['name']
print(name)
movie_id = movie.insert({'name':name})
new_movie = movie.find_one({'_id': movie_id })
output = {'name' : new_movie['name']}
return jsonify({'result' : output})
except TypeError:
return jsonify({'result' : 'niet'})
and my POST request is made with an AJAX request in one of my template :
$(document).ready(function() {
$('#movies_btn').click(function() {
$.ajax({
url: "{{ url_for('add_movie') }}",
type: 'POST',
contentType: 'application/json;charset=UTF-8',
data: JSON.stringify({'name':'oui'}),
success: res => {
alert('stop')
window.location.href="{{ url_for('index') }}"
},
error: xhr => {
alert(xhr.responseText.split('\n')[1])
}
})
})
})
Can you help me with this issue? I tried to look at the documentation of flask pymongo but I don't find the answer.
Thanks
