APIv3 PUT issue 4001 Invalid input

APIv3 PUT issue 4001 Invalid input

Hi, I'm tring to update any data on ASSETS but always failed, what can be wrong?
API key have SDAdmin role, so it's maximum role

#Python version - 3.8
#This script requires requests module installed in python.
import requests
 
headers ={"authtoken":"REAL-API-TOKEN"}
input_data = '''{
    "asset":{
        "department":{
            "name": "DepA"
        }
    }
}'''
data = {'input_data': input_data}
response = requests.put(url,headers=headers,data=data,verify=False)
print(response.text)


and responce is 
{"response_status":{"status_code":4000,"messages":[{"status_code":4001,"field":"department","type":"failed","message":"Invalid input"}],"status":"failed"}}

I have checked that 4001 error is Id or Name given in Input does not exist or not in use or user cannot set the value
User can not set the Value? strange... it's maximum rights user. 

I did same on different languages, JavaScript, PowerShell, python, but still failed. 
Any advice will be helpfull.

SD version is 14201
