How to send russian characters in jira put request?

Question

Python

I'm trying to execute the following request, but I'm getting a 500 error in response:

import requests
data = 'Отдел разработки'.encode('utf-8')
response = requests.put('https://jira.citilink.ru/rest/greenhopper/1.0/rapidviewconfig/name', data=data,
                   auth=HTTPBasicAuth(login, password),
                   headers={'Content-Type':'application/json', 'charset':'utf8'})

At first, without encoding and headers, there was an error 415
