I was studying rails and following the link tutorial.

The steps in the tutorial were as follows, create a datatable that would make a request via json, the controller that would respond with the data and the data table would be populated.

At the time of the test I received the following server error: 406 Not Acceptable, and detailing the chrome error in the network tab, the following error is displayed:

ActionController :: UnknownFormat at /categories.json%20

  

ActionController :: UnknownFormat

app / controllers / categories_controller.rb, line 8

'' 'ruby     3 before_action: set_category, only: [: show,: edit,: update,: destroy]     4
    5 # GET / categories     6 # GET /categories.json     7 def index

  

8 respond_to do | format |       9 format.html      10 format.json {render json: CategoryDatatable.new (view_context)}      11 end      12 end      13   '' '

I searched but could not find or find a solution.

The following is a step-by-step guide to the code if someone can help me:
