Not able to add new file using bitbucket server api.

Also please help me in repairing my code. 

auth is repository access token

from variables import base_url,repo,file,username,auth

import requests
import json

url = f"http://{base_url}/rest/api/latest/projects/~{username}/repos/{repo}/browse/{file}"

contents=None
with open(file,"r") as f:
    contents=f.read()

payload={
  "branch": "master",
  "content": contents,
  "message": "Holla",
  "sourceCommitId": None
}

headers = {
    "Accept": "application/json",
    "Authorization": f"Bearer {auth}",
    "Content-Type": "multipart/form-data"
}

response = requests.request(
"PUT",
 url,
 headers=headers,
