Reset password redirects to undefined URL (missing config)

[mikurisan]

What happened?

After I configured SMTP and went to the "Forget password" page, the following error occurred.

The page redirected to https://host/undefined/reset-password?token=xxxx

I removed the undefined from the URL and then I can access it.
