How do I get the value of URL from PUT request? In Ruby

Question

What I need is the value of URL from the PUT request. Here is the result of the PUT request. Response: {"result":{"attempts":1,"url":null}}

I can't tell where is the problem.

loop do
  response = HTTParty.put("#{API_ENDPOINT}/challenges", headers: { 'X-Challenge-Id' => challenge_id })
  puts "Response: #{response}"

  if response['error']
    puts "Error: #{response['error']}"
  elsif response.key?('result')
    result = response['result']
    attempts = result['attempts']
    url = result['url']
    if attempts.zero?
      puts "Challenge failed. Attempts: #{attempts}"
    elsif url.nil?
      puts "Challenge succeeded but no URL available. Attempts: #{attempts}"
    else
      puts "Challenge succeeded. Attempts: #{attempts}"
      puts "URL with keyword: #{API_ENDPOINT}#{url}"
    end

    break
  end
end

The thing I want to do, Start a challenge by making a POST HTTP request to/challenges. At the scheduled invocation time (actives_at) time in the response, an HTTP request is sent as PUT to/challenges. At this time, it is necessary to give the challenge ID (id) to the X-Challenge-Id header.

I tried to print out the error message but seems the challenge succeeded just no URL available.

You need parse JSON from string to hash

json_response = HTTParty.put("#{API_ENDPOINT}/challenges", headers: { 'X-Challenge-Id' => challenge_id })

response = JSON.parse(json_response.body, symbolize_names: true)

After that you can process response

if response[:error]
  puts "Error: #{response[:error]}"
elsif response[:result]
  attempts = response[:result][:attempts]
  url = response[:result][:url]

  if attempts.zero?
    puts "Challenge failed. Attempts: #{attempts}"
  elsif url.nil?
    puts "Challenge succeeded but no URL available. Attempts: #{attempts}"
  else
    puts "Challenge succeeded. Attempts: #{attempts}"
    puts "URL with keyword: #{API_ENDPOINT}#{url}"
  end
end
