[difemaro]

Describe the bug
I am trying to create or modify a user, and I have not been able to. I receive different error.

Versions
Details of your environment, including:

• Tableau Server version 2023.1.4
• Python version 3.10.6
• TSC library version: 0.25

To Reproduce
I am running two codes:
Code 1 Creating User

import tableauserverclient as TSC
 
TOKEN_NAME = "tokenname"
TOKEN = "S4dD5AVINzA==:aQp3EPJy09Cf3d"
SERVER_NAME = 'https://www.yourserver.com/'
SITE_NAME = 'yoursitename'
 
tableau_auth = TSC.PersonalAccessTokenAuth(TOKEN_NAME,TOKEN,SITE_NAME)
server = TSC.Server(SERVER_NAME, use_server_version=True)

with server.auth.sign_in(tableau_auth):
    print("Signed in")
    # create a new user_item
    user1 = TSC.UserItem('temp', 'Viewer')

    # add new user
    user1 = server.users.add(user1)
    print(user1.name, user1.site_role, user1.id)

    # modify user info
    user1.name = 'Laura'
    user1.fullname = 'Laura Rodriguez'
    user1.email = 'laura@example.com'

    # update user
    server.users.update(user1)
    print("Updated user info:")
    print(user1.name, user1.fullname, user1.email, user1.id)

# Sign out
server.auth.sign_out()  

Code 2 Modifying User

import tableauserverclient as TSC
 
TOKEN_NAME = "tokenname"
TOKEN = "S4dD5AVINzA==:aQp3EPJy09Cf3d"
SERVER_NAME = 'https://www.yourserver.com/'
SITE_NAME = 'yoursitename'
 
tableau_auth = TSC.PersonalAccessTokenAuth(TOKEN_NAME,TOKEN,SITE_NAME)
server = TSC.Server(SERVER_NAME, use_server_version=True)
NEW_DOMAIN = '@newdomain.com'
with server.auth.sign_in(tableau_auth):
   print("Signed in")
   for t in TSC.Pager(server.users):
        if t.site_role != "ServerAdministrator":
            email = t.email
            new_email = email.split("@")[0] + NEW_DOMAIN
            t.email = new_email
            server.users.update(t)

# Sign out
server.auth.sign_out()
