How to get a selected list of GitHub issues in octocat with Ruby?

Question

Basically I am using octokit trying to add a particular set of GitHub issues, based on their issue number, to an issue list.

The summary of the code is similar to this:

require 'octokit'

client = Octokit::Client.new(access_token: ENV['GITHUB_OAUTH_TOKEN'], accept: 'application/vnd.github.v3+json')

REPO = 'USERNAME/SOME-GH-REPO'.freeze

#client.issue(REPO, 1)                     # Returns {}
#client.issues(REPO, :state => 'all')      # Returns [{}]

def pull_source_issues
    @client.auto_paginate = true

    ilist =[1,2,3]
    my_array = []

    ilist.each do |i|
        puts "Adding issue [#]: #{i} \t from: #{REPO}\n"
        my_array.push(@client.issue(REPO , "#{i}", :state => 'all'))   # works
        #@issues.push(@client.issue(REPO , "#{i}", :state => 'all'))   # fails!
    end
    @issues = my_array

    puts "Found #{issues.size} issues."
end

But it seem that I have to use the intermediate my_array, as pushing into @issues array immediately, fails.

Drawback

This way also seem very inefficient as I seem to make a request for each item, instead of fetching them all at the same time and then select the ones needed. In addition it also selects for pull requests, which is not wanted. (*Because PR's are also issues in GH.)

I often see the iterator looking like this:

@issues = @client.issues(@source_repo, :state => 'all')

@issues.each do |source_issue|
    print "Processing issue: #{source_issue.number}  (#{n}/#{issues.size})\r"
    if !source_issue.key?(:pull_request) || source_issue.pull_request.empty?
        # Add each issue to (new?) @issues here
    end
end

But I can't get that to work either.

How can I push() each issue into the @issues array immediately?
(And how can I do it more efficiently?)
