Failed to access chrome messaging API from execute_script selenium

I need to send a value for the chrome extension from a browser automation script. The way I'm currently trying to do this is to try calling the chrome.runtime.sendMessage API from selenium to tell the value of the chrome extension. Python code:

import os
import time
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options



chrome_options = Options()
chrome_options.add_extension('/home/lurscher/plugin.crx')
browser = webdriver.Chrome(chrome_options=chrome_options)
browser.get(url)
browser.execute_script("chrome.runtime.sendMessage({someValue: "+str(args.value)+"}, function(response) { console.log('value sent. '+response)})")

I get this error:

Traceback (most recent call last):
  File "tools/selenium/open_page.py", line 17, in <module>
    browser.execute_script("chrome.runtime.sendMessage({someValue: "+str(args.value)+"}, function(response) { console.log('value sent. '+response)})")
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 397, in execute_script
    {'script': script, 'args':converted_args})['value']
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 165, in execute
    self.error_handler.check_response(response)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/errorhandler.py", line 164, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: u"unknown error: Cannot call method 'sendMessage' of undefined\n  (Session info: chrome=28.0.1500.71)\n  (Driver info: chromedriver=2.1,platform=Linux 3.5.0-17-generic x86_64)"

Question: Any idea what I'm doing wrong?
