Devise - undefined local variable or method `current_member' - ruby-on-rails

Question

I am using members as the Devise model. I have placed before_action :authenticate_member! in the application controller.
But when i try to use the following in the views
<%= current_member.inspect %>
Am getting the following error
undefined local variable or method `current_member' for #<#<Class:0x007fe48ad32130>:0x007fe48e389af8>
#<Class:0x007fe48ad32130>#_app_views_brands_members_index_html_erb___144793605481589474_70309807670200

<%= current_member.inspect %>
