XMLHttpRequest cannot load http: // localhost: 3000 / players / 1. Preflight response has invalid HTTP 404 status code

I am creating react app with rails api. I have a player_controller with create, index, update actions. I can do everything (create, index, update) from the postman. But when I tried a fetch request from react action. I could only index and create a player model. On upgrade, I get this error in the debugger console.

:3000/players/1:1 OPTIONS http://localhost:3000/players/1
XMLHttpRequest cannot load http://localhost:3000/players/1. Response 
for preflight has invalid HTTP status code 404

      

        
        
        
      

    

in Rails my players_controller.rb

class PlayersController < ApplicationController
 skip_before_action :verify_authenticity_token
 respond_to :json
 def index
  @players = Player.find_by(player_id: params[:player_id])
  player = Player.all
  render json: @players
 end
def create
  player = Player.new(player_params)
  if player.save
    render json: player, status: 201
  else
  render json: { errors: player.errors }, status: 422
  end
end

def update
 player = Player.find(params[:id])
 player.update(player_params)
 if player.save
   render json: player, status: 201
 else
 render json: { errors: player.errors }, status: 422
 end
end

private

def player_params
 params.require(:player).permit(:username, :profile_pic, :player_id)
end
end

      

        
        
        
      

    

In my react based app I have an action

export const profilePicUpdate = (player, profile) => (dispatch) => {
const obj = player;
obj.profile_pic = profile;
fetch(`http://localhost:3000/players/${player.id}`, {
  method: 'PATCH',
  headers: {
    Accept: 'application/json',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    obj
  })
}).then(() => {
  dispatch({
    type: 'PROFILE_PIC_UPDATE',
    payload: profile
  });
  NavigatorService.navigate('Profile');
}).catch((error) => {
  console.log('Error', error);
});
};
