As an admin in Odoo 18 Community Edition, I sent a Reset Password link to one of the users.

When the user clicks the link and resets their password, the following error message appears:

"Expected singleton: res.users('uid', 'auth_method', 'mfa')"

However, despite the error, the user remains on the Reset Password page, but they are already logged into the system, and their password has actually been changed successfully.

Notes:

• The user is successfully authenticated and can access Odoo after refreshing.
• This issue only occurs after using the Reset Password process.

Questions:

• Why does this error appear?
• How can this issue be resolved to prevent the error message from showing?

Environment:

• Odoo Version: 18 Community Edition
• Local server
• Authentication Setup: Standard (no third-party modules for login or MFA)
