`fetch': key not found: "data" (KeyError) : graphql-client error - ruby

Question

I was trying to use the graphql query within ruby to fetch github repositories. Before writing the query, I was working on getting the graphql-client working. I'm facing issues with graphql client.
I was following this link for graphql client:
https://github.com/github/graphql-client
require 'graphql'
require 'graphql/client'
require 'graphql/client/http'
module MyGraphQL
HTTP = GraphQL::Client::HTTP.new('https://github.com/graphql') do
def client_context
{ access_token: 'xxxxxxxxxxxxxxxxxx' }
end
def headers(_context)
client_context
end
end
Schema = GraphQL::Client.load_schema(HTTP)
Client = GraphQL::Client.new(schema: Schema, execute: HTTP)
end
I'm getting the following errors in a terminal:
'fetch': key not found: "data" (KeyError)
'load'
'load_schema'
'load_schema'

Answer 1

This error appears due to response you receive via fetching https://github.com/graphql.
You can use binding.pry (this gem), for example, to see what happening, when you try to run load_schema method.
It tries to fetch data from response here: http://i.imgur.com/9T9WRUu.png
But there is no data attribute, because you get {"errors"=>[{"message"=>"422 Unprocessable Entity"}]}
Try to fetch http://graphql-swapi.parseapp.com/, for example, worked for me.

Also faced with same problem. Replacing body method to this helped:
def headers(context)
{
"Authorization" => "bearer #{TOKEN}"
}
end
Where is the TOKEN is the Personal access token gotten from here: https://github.com/settings/tokens
