ActionView::SyntaxErrorInTemplate in Devise::SessionsController#new

Encountered a syntax error while rendering template: check - flash.each do |name, msg| - if msg.is_a?(String) %br %div{:class => "alert alert-#{name.to_s == 'notice' ? 'success' : 'danger'}"} %button.close{"aria-hidden" => "true", "data-dismiss" => "alert", :type => "button"} × = content_tag :div, msg, :id => "flash_#{name}"

My devise template devise.html.haml app/views/layouts/devise.html.haml

!!!
%html
    %head
        %meta{:content => "text/html; charset=UTF-8", "http-equiv" => "Content-Type"}/
        %title Tasker
        = csrf_meta_tags
        = csp_meta_tag
        = javascript_pack_tag 'application', 'data-turbolinks-track': 'reload'
        = stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload'
    %body
        .container
            .main-flash-messages
                = render 'layouts/messages'
        .fullscreen
            .container
                = yield

My partial _messages.html.haml app/views/layouts/_messages.html.haml

- flash.each do |name, msg|
    - if msg.is_a?(String)
    %br
    %div{:class => "alert alert-#{name.to_s == 'notice' ? 'success' : 'danger'}"}
        %button.close{"aria-hidden" => "true", "data-dismiss" => "alert", :type => "button"} ×
        = content_tag :div, msg, :id => "flash_#{name}"

I tryed to solve this reading the documentation of haml but i don't know what is wrong. Regards.

I am not familiar with HAML but I expect that the content that depends on the if condition needs to be indented and would therefore try:

- flash.each do |name, msg|
  - if msg.is_a?(String)
    %br
    %div{:class => "alert alert-#{name.to_s == 'notice' ? 'success' : 'danger'}"}
      %button.close{"aria-hidden" => "true", "data-dismiss" => "alert", :type => "button"} ×
      = content_tag :div, msg, :id => "flash_#{name}"
