Hi! I am getting the error "Missing required element [Password]" (UserMessageIfMissingRequiredElement) in our custom policy for SignIn when user input is only whitespace and I do not understand why. The element in question does in fact have an input (even though it's only whitespaces) so it should not be missing? Shouldn't this result in some invalid error like UserMessageIfInvalidPassword or atleast DefaultMessage instead? See images below for reference. User's image

Thanks, Viktor.

    Hi @Viktor Lindstedt , this is expected behavior. The error is thrown because the input contains no valid elements. UserMessageIfInvalidPassword is if the password is incorrect. The linked page details more examples. Please let me know if you have any questions and I can help you further. If this answer helps you please mark "Accept Answer" so other users can reference it.

    Thank you,

    James
