No route matches {:action=>"show", :controller=>"spree/taxons", :id=>nil}

Question

Hello RoR programmers,

I get stuck in customized spree application codes brought errors after upgrade to rails 5.1.5.

puma logged this error:

Error during failsafe response: No route matches {:action=>"show", :controller=>"spree/taxons", :id=>nil}, possible unmatched constraints: [:id]

main_nav_bar.html.erb worked on rails 4.2.

Any help is appreciated.

try this route:

 get '/t/*id', to: 'spree/taxons#show', as: :nested_taxons
