If you get following error when trying to parse time:

Time.zone.parse('2019-01-01 11:11:11')

Traceback (most recent call last):

NoMethodError (undefined method `parse' for nil:NilClass)

it means you've forgotten to set the timezone:

Time.zone = 'UTC'

Also, keep in mind, that each time you spin up a new thread, it won't have a timezone defined (outside of Rails):

Time.zone = 'UTC'

Time.zone.parse('2019-01-01 11:11:11') # works

Thread.abort_on_exception = true

# fails
Thread.new do
  Time.zone.parse('2019-01-01 11:11:11')
end

# NoMethodError: undefined method `parse' for nil:NilClass

In order to fix that, you need to set the time zone in each of your newly created threads:

Time.zone = 'UTC'

Time.zone.parse('2019-01-01 11:11:11') # works

Thread.abort_on_exception = true

# works
Thread.new do
  Time.zone = 'UTC'
  Time.zone.parse('2019-01-01 11:11:11')
end

A short snippet on how to make Ruby on Rails authenticate_or_request_with_http_basic respond with a JSON valid message upon failure.

class ApplicationController < ActionController::API
  include(
    ActionController::HttpAuthentication::Basic::ControllerMethods
  )

  before_action :http_authenticate!

  def http_authenticate!
    authenticate_or_request_with_http_basic do |key, secret|
      return if Resource.find_by(
        key: key,
        secret: secret
      )
    end

    render(
      json: 'Invalid credentials'.to_json,
      status: 401
    )
  end
end
