ActionController::RoutingError: No route matches [POST] \"/graphql\"

[leosoaivan]

I'm currently learning Rails API-only development and versioning, and I'd like to implement GraphQL and play with GraphiQL. I'm currently getting the error above. It's probably a simple issue, and I apologize, but I'm stuck.

My routes are as follows:

Rails.application.routes.draw do
  if Rails.env.development?
    mount GraphiQL::Rails::Engine, at: "/graphiql", graphql_path: "/graphql"
  end

  scope module: :v3, constraints: ApiVersion.new('v3') do
    post 'graphql', to: 'graphql#execute'
  end  

  scope module: :v2, constraints: ApiVersion.new('v2') do
    resources :todos, only: :index
  end

  scope module: :v1, constraints: ApiVersion.new('v1', true) do
    resources :todos do
      resources :items
    end
  end

  post 'auth/login', to: 'authentication#authenticate'
  post 'signup',     to: 'users#create'
end

Thanks in advance. Any insight would be appreciated.

Figured it out. It seems the post route shouldn't have been nested. Closing!

I'm getting the same error. Can you tell me what solved the problem? These are my routes:

Rails.application.routes.draw do
  if Rails.env.development?
    mount GraphiQL::Rails::Engine, at: "/graphiql", graphql_path: "/graphql"
  end
  post "/graphql", to: "graphql#execute"
  # Define your application routes per the DSL in https://guides.rubyonrails.org/routing.html

  # Defines the root path route ("/")
  # root "articles#index"
end
