Deface::DSL does not know how to read '/store/app/overrides/spree/order_mailer/confirm_email.text/append_text.text.erb.deface'. Override files should end with just .deface, .html.erb.deface, .html.haml.deface or .html.slim.deface
<!-- insert_after "erb:contains('order_mailer.confirm_email.thanks')" -->
My text I want to insert
$ bundle exec rake deface:test_selector['spree/order_mailer/confirm_email.text',"erb:contains('order_mailer.confirm_email.thanks')"]
Querying 'spree/order_mailer/confirm_email.text' for 'erb:contains('order_mailer.confirm_email.thanks')'
---------------- Match 1 ----------------
<%= Spree.t('order_mailer.confirm_email.thanks') %>
