This may be a cypress test bug or a core bug - I dont know

npx cypress run --spec '.\tests\System\integration\api\com_users\Users.cy.js'

Test runs successfully but the php error log contains the following warning

[24-Feb-2025 19:25:27 UTC] PHP Warning: Undefined array key "password2" in D:\repos\j51\administrator\components\com_users\src\Model\UserModel.php on line 295
